Merge tag 'staging-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO driver updates from Greg KH:
 "Here is the big set of staging and IIO driver updates for 5.13-rc1.

  Lots of little churn in here, and some larger churn as well. Major
  things are:

   - removal of wimax drivers, no one has this hardware anymore for this
     failed "experiment".

   - removal of the Google gasket driver, turns out no one wanted to
     maintain it or cares about it anymore, so they asked for it to be
     removed.

   - comedi finally moves out of the staging directory into drivers/comedi

     This is one of the oldest kernel subsystems around, being created
     in the 2.0 kernel days, and was one of the first things added to
     drivers/staging/ when that was created over 15 years ago.

     It should have been moved out of staging a long time ago, it's well
     maintained and used by loads of different devices in the real world
     every day. Nice to see this finally happen.

   - so many tiny coding style cleanups it's not funny.

     Perfect storm of at least 2 different intern project application
     deadlines combined to provide a huge number of new contributions in
     this area from people learning how to do kernel development. Great
     job to everyone involved here.

  There's also the normal updates for IIO drivers with new IIO drivers
  and updates all over that subsystem.

  All of these have been in linux-next for a while with no reported
  issues"

-This is a list of things that need to be done to get this driver out of the
-staging directory.
-
-- Implement the gasket framework's functionality through UIO instead of
-  introducing a new user-space drivers framework that is quite similar.
-
-  UIO provides the necessary bits to implement user-space drivers. Meanwhile
-  the gasket APIs adds some extra conveniences like PCI BAR mapping, and
-  MSI interrupts. Add these features to the UIO subsystem, then re-implement
-  the Apex driver as a basic UIO driver instead (include/linux/uio_driver.h)
-
-- Document sysfs files with Documentation/ABI/ entries.
-
-- Use misc interface instead of major number for driver version description.
-
-- Add descriptions of module_param's
-
-- apex_get_status() should actually check status.
-
-- "drivers" should never be dealing with "raw" sysfs calls or mess around with
-  kobjects at all. The driver core should handle all of this for you
-  automaically. There should not be a need for raw attribute macros.

- * Implementation of Gasket page table support.
- *
- * This file assumes 4kB pages throughout; can be factored out when necessary.
- *
- * There is a configurable number of page table entries, as well as a
- * configurable bit index for the extended address flag. Both of these are
- * specified in gasket_page_table_init through the page_table_config parameter.
- *
- * The following example assumes:
- *   page_table_config->total_entries = 8192
- *   page_table_config->extended_bit = 63
- *
- * Address format:
- * Simple addresses - those whose containing pages are directly placed in the
- * device's address translation registers - are laid out as:
- * [ 63 - 25: 0 | 24 - 12: page index | 11 - 0: page offset ]
- * page index:  The index of the containing page in the device's address
- *              translation registers.
- * page offset: The index of the address into the containing page.
- *
- * Extended address - those whose containing pages are contained in a second-
- * level page table whose address is present in the device's address translation
- * registers - are laid out as:
- * [ 63: flag | 62 - 34: 0 | 33 - 21: dev/level 0 index |
- *   20 - 12: host/level 1 index | 11 - 0: page offset ]
- * flag:        Marker indicating that this is an extended address. Always 1.
- * dev index:   The index of the first-level page in the device's extended
- *              address translation registers.
- * host index:  The index of the containing page in the [host-resident] second-
- *              level page table.
- * page offset: The index of the address into the containing [second-level]
- *              page.

-====================================================
-Driver for the Intel Wireless Wimax Connection 2400m
-====================================================
-
-:Copyright: |copy| 2008 Intel Corporation < linux-wimax@intel.com >
-
-   This provides a driver for the Intel Wireless WiMAX Connection 2400m
-   and a basic Linux kernel WiMAX stack.
-
-1. Requirements
-===============
-
-     * Linux installation with Linux kernel 2.6.22 or newer (if building
-       from a separate tree)
-     * Intel i2400m Echo Peak or Baxter Peak; this includes the Intel
-       Wireless WiMAX/WiFi Link 5x50 series.
-     * build tools:
-
-          + Linux kernel development package for the target kernel; to
-            build against your currently running kernel, you need to have
-            the kernel development package corresponding to the running
-            image installed (usually if your kernel is named
-            linux-VERSION, the development package is called
-            linux-dev-VERSION or linux-headers-VERSION).
-          + GNU C Compiler, make
-
-2. Compilation and installation
-===============================
-
-2.1. Compilation of the drivers included in the kernel
-------------------------------------------------------
-
-   Configure the kernel; to enable the WiMAX drivers select Drivers >
-   Networking Drivers > WiMAX device support. Enable all of them as
-   modules (easier).
-
-   If USB or SDIO are not enabled in the kernel configuration, the options
-   to build the i2400m USB or SDIO drivers will not show. Enable said
-   subsystems and go back to the WiMAX menu to enable the drivers.
-
-   Compile and install your kernel as usual.
-
-2.2. Compilation of the drivers distributed as an standalone module
--------------------------------------------------------------------
-
-   To compile::
-
-	$ cd source/directory
-	$ make
-
-   Once built you can load and unload using the provided load.sh script;
-   load.sh will load the modules, load.sh u will unload them.
-
-   To install in the default kernel directories (and enable auto loading
-   when the device is plugged)::
-
-	$ make install
-	$ depmod -a
-
-   If your kernel development files are located in a non standard
-   directory or if you want to build for a kernel that is not the
-   currently running one, set KDIR to the right location::
-
-	$ make KDIR=/path/to/kernel/dev/tree
-
-   For more information, please contact linux-wimax@intel.com.
-
-3. Installing the firmware
---------------------------
-
-   The firmware can be obtained from http://linuxwimax.org or might have
-   been supplied with your hardware.
-
-   It has to be installed in the target system::
-
-	$ cp FIRMWAREFILE.sbcf /lib/firmware/i2400m-fw-BUSTYPE-1.3.sbcf
-
-     * NOTE: if your firmware came in an .rpm or .deb file, just install
-       it as normal, with the rpm (rpm -i FIRMWARE.rpm) or dpkg
-       (dpkg -i FIRMWARE.deb) commands. No further action is needed.
-     * BUSTYPE will be usb or sdio, depending on the hardware you have.
-       Each hardware type comes with its own firmware and will not work
-       with other types.
-
-4. Design
-=========
-
-   This package contains two major parts: a WiMAX kernel stack and a
-   driver for the Intel i2400m.
-
-   The WiMAX stack is designed to provide for common WiMAX control
-   services to current and future WiMAX devices from any vendor; please
-   see README.wimax for details.
-
-   The i2400m kernel driver is broken up in two main parts: the bus
-   generic driver and the bus-specific drivers. The bus generic driver
-   forms the drivercore and contain no knowledge of the actual method we
-   use to connect to the device. The bus specific drivers are just the
-   glue to connect the bus-generic driver and the device. Currently only
-   USB and SDIO are supported. See drivers/net/wimax/i2400m/i2400m.h for
-   more information.
-
-   The bus generic driver is logically broken up in two parts: OS-glue and
-   hardware-glue. The OS-glue interfaces with Linux. The hardware-glue
-   interfaces with the device on using an interface provided by the
-   bus-specific driver. The reason for this breakup is to be able to
-   easily reuse the hardware-glue to write drivers for other OSes; note
-   the hardware glue part is written as a native Linux driver; no
-   abstraction layers are used, so to port to another OS, the Linux kernel
-   API calls should be replaced with the target OS's.
-
-5. Usage
-========
-
-   To load the driver, follow the instructions in the install section;
-   once the driver is loaded, plug in the device (unless it is permanently
-   plugged in). The driver will enumerate the device, upload the firmware
-   and output messages in the kernel log (dmesg, /var/log/messages or
-   /var/log/kern.log) such as::
-
-	...
-	i2400m_usb 5-4:1.0: firmware interface version 8.0.0
-	i2400m_usb 5-4:1.0: WiMAX interface wmx0 (00:1d:e1:01:94:2c) ready
-
-   At this point the device is ready to work.
-
-   Current versions require the Intel WiMAX Network Service in userspace
-   to make things work. See the network service's README for instructions
-   on how to scan, connect and disconnect.
-
-5.1. Module parameters
-----------------------
-
-   Module parameters can be set at kernel or module load time or by
-   echoing values::
-
-	$ echo VALUE > /sys/module/MODULENAME/parameters/PARAMETERNAME
-
-   To make changes permanent, for example, for the i2400m module, you can
-   also create a file named /etc/modprobe.d/i2400m containing::
-
-	options i2400m idle_mode_disabled=1
-
-   To find which parameters are supported by a module, run::
-
-	$ modinfo path/to/module.ko
-
-   During kernel bootup (if the driver is linked in the kernel), specify
-   the following to the kernel command line::
-
-	i2400m.PARAMETER=VALUE
-
-5.1.1. i2400m: idle_mode_disabled
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   The i2400m module supports a parameter to disable idle mode. This
-   parameter, once set, will take effect only when the device is
-   reinitialized by the driver (eg: following a reset or a reconnect).
-
-5.2. Debug operations: debugfs entries
---------------------------------------
-
-   The driver will register debugfs entries that allow the user to tweak
-   debug settings. There are three main container directories where
-   entries are placed, which correspond to the three blocks a i2400m WiMAX
-   driver has:
-
-     * /sys/kernel/debug/wimax:DEVNAME/ for the generic WiMAX stack
-       controls
-     * /sys/kernel/debug/wimax:DEVNAME/i2400m for the i2400m generic
-       driver controls
-     * /sys/kernel/debug/wimax:DEVNAME/i2400m-usb (or -sdio) for the
-       bus-specific i2400m-usb or i2400m-sdio controls).
-
-   Of course, if debugfs is mounted in a directory other than
-   /sys/kernel/debug, those paths will change.
-
-5.2.1. Increasing debug output
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   The files named *dl_* indicate knobs for controlling the debug output
-   of different submodules::
-
-	# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
-	/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_tx
-	/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_rx
-	/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_notif
-	/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_fw
-	/sys/kernel/debug/wimax:wmx0/i2400m-usb/dl_usb
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_tx
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_rx
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_rfkill
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_netdev
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_fw
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_debugfs
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_driver
-	/sys/kernel/debug/wimax:wmx0/i2400m/dl_control
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_stack
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs
-
-   By reading the file you can obtain the current value of said debug
-   level; by writing to it, you can set it.
-
-   To increase the debug level of, for example, the i2400m's generic TX
-   engine, just write::
-
-	$ echo 3 > /sys/kernel/debug/wimax:wmx0/i2400m/dl_tx
-
-   Increasing numbers yield increasing debug information; for details of
-   what is printed and the available levels, check the source. The code
-   uses 0 for disabled and increasing values until 8.
-
-5.2.2. RX and TX statistics
-^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   The i2400m/rx_stats and i2400m/tx_stats provide statistics about the
-   data reception/delivery from the device::
-
-	$ cat /sys/kernel/debug/wimax:wmx0/i2400m/rx_stats
-	45 1 3 34 3104 48 480
-
-   The numbers reported are:
-
-     * packets/RX-buffer: total, min, max
-     * RX-buffers: total RX buffers received, accumulated RX buffer size
-       in bytes, min size received, max size received
-
-   Thus, to find the average buffer size received, divide accumulated
-   RX-buffer / total RX-buffers.
-
-   To clear the statistics back to 0, write anything to the rx_stats file::
-
-	$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m_rx_stats
-
-   Likewise for TX.
-
-   Note the packets this debug file refers to are not network packet, but
-   packets in the sense of the device-specific protocol for communication
-   to the host. See drivers/net/wimax/i2400m/tx.c.
-
-5.2.3. Tracing messages received from user space
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   To echo messages received from user space into the trace pipe that the
-   i2400m driver creates, set the debug file i2400m/trace_msg_from_user to
-   1::
-
-	$ echo 1 > /sys/kernel/debug/wimax:wmx0/i2400m/trace_msg_from_user
-
-5.2.4. Performing a device reset
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   By writing a 0, a 1 or a 2 to the file
-   /sys/kernel/debug/wimax:wmx0/reset, the driver performs a warm (without
-   disconnecting from the bus), cold (disconnecting from the bus) or bus
-   (bus specific) reset on the device.
-
-5.2.5. Asking the device to enter power saving mode
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-   By writing any value to the /sys/kernel/debug/wimax:wmx0 file, the
-   device will attempt to enter power saving mode.
-
-6. Troubleshooting
-==================
-
-6.1. Driver complains about ``i2400m-fw-usb-1.2.sbcf: request failed``
-----------------------------------------------------------------------
-
-   If upon connecting the device, the following is output in the kernel
-   log::
-
-	i2400m_usb 5-4:1.0: fw i2400m-fw-usb-1.3.sbcf: request failed: -2
-
-   This means that the driver cannot locate the firmware file named
-   /lib/firmware/i2400m-fw-usb-1.2.sbcf. Check that the file is present in
-   the right location.

-========================
-Linux kernel WiMAX stack
-========================
-
-:Copyright: |copy| 2008 Intel Corporation < linux-wimax@intel.com >
-
-   This provides a basic Linux kernel WiMAX stack to provide a common
-   control API for WiMAX devices, usable from kernel and user space.
-
-1. Design
-=========
-
-   The WiMAX stack is designed to provide for common WiMAX control
-   services to current and future WiMAX devices from any vendor.
-
-   Because currently there is only one and we don't know what would be the
-   common services, the APIs it currently provides are very minimal.
-   However, it is done in such a way that it is easily extensible to
-   accommodate future requirements.
-
-   The stack works by embedding a struct wimax_dev in your device's
-   control structures. This provides a set of callbacks that the WiMAX
-   stack will call in order to implement control operations requested by
-   the user. As well, the stack provides API functions that the driver
-   calls to notify about changes of state in the device.
-
-   The stack exports the API calls needed to control the device to user
-   space using generic netlink as a marshalling mechanism. You can access
-   them using your own code or use the wrappers provided for your
-   convenience in libwimax (in the wimax-tools package).
-
-   For detailed information on the stack, please see
-   include/linux/wimax.h.
-
-2. Usage
-========
-
-   For usage in a driver (registration, API, etc) please refer to the
-   instructions in the header file include/linux/wimax.h.
-
-   When a device is registered with the WiMAX stack, a set of debugfs
-   files will appear in /sys/kernel/debug/wimax:wmxX can tweak for
-   control.
-
-2.1. Obtaining debug information: debugfs entries
--------------------------------------------------
-
-   The WiMAX stack is compiled, by default, with debug messages that can
-   be used to diagnose issues. By default, said messages are disabled.
-
-   The drivers will register debugfs entries that allow the user to tweak
-   debug settings.
-
-   Each driver, when registering with the stack, will cause a debugfs
-   directory named wimax:DEVICENAME to be created; optionally, it might
-   create more subentries below it.
-
-2.1.1. Increasing debug output
-------------------------------
-
-   The files named *dl_* indicate knobs for controlling the debug output
-   of different submodules of the WiMAX stack::
-
-	# find /sys/kernel/debug/wimax\:wmx0 -name \*dl_\*
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_stack
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_rfkill
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_reset
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_op_msg
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
-	/sys/kernel/debug/wimax:wmx0/wimax_dl_debugfs
-	/sys/kernel/debug/wimax:wmx0/.... # other driver specific files
-
-   NOTE:
-       Of course, if debugfs is mounted in a directory other than
-       /sys/kernel/debug, those paths will change.
-
-   By reading the file you can obtain the current value of said debug
-   level; by writing to it, you can set it.
-
-   To increase the debug level of, for example, the id-table submodule,
-   just write:
-
-	$ echo 3 > /sys/kernel/debug/wimax:wmx0/wimax_dl_id_table
-
-   Increasing numbers yield increasing debug information; for details of
-   what is printed and the available levels, check the source. The code
-   uses 0 for disabled and increasing values until 8.

-There are no known users of this driver as of October 2020, and it will
-be removed unless someone turns out to still need it in future releases.
-
-According to https://en.wikipedia.org/wiki/List_of_WiMAX_networks, there
-have been many public wimax networks, but it appears that many of these
-have migrated to LTE or discontinued their service altogether.  As most
-PCs and phones lack WiMAX hardware support, the remaining networks tend
-to use standalone routers. These almost certainly run Linux, but not a
-modern kernel or the mainline wimax driver stack.
-
-NetworkManager appears to have dropped userspace support in 2015
-https://bugzilla.gnome.org/show_bug.cgi?id=747846, the www.linuxwimax.org
-site had already shut down earlier.
-
-WiMax is apparently still being deployed on airport campus networks
-("AeroMACS"), but in a frequency band that was not supported by the old
-Intel 2400m (used in Sandy Bridge laptops and earlier), which is the
-only driver using the kernel's wimax stack.

- *           has to start with a &struct i2400M_l3l4_hdr and then
- *           followed by the payload. Once this function returns, the
- *           buffer can be reused.
- *
- * @buf_len: buffer size
- *
- * Returns:
- *
- * Pointer to skb containing the ack message. You need to check the
- * pointer with IS_ERR(), as it might be an error code. Error codes
- * could happen because:
- *
- *  - the message wasn't formatted correctly
- *  - couldn't send the message
- *  - failed waiting for a response
- *  - the ack message wasn't formatted correctly
- *
- * The returned skb has been allocated with wimax_msg_to_user_alloc(),
- * it contains the response in a netlink attribute and is ready to be
- * passed up to user space with wimax_msg_to_user_send(). To access
- * the payload and its length, use wimax_msg_{data,len}() on the skb.
- *
- * The skb has to be freed with kfree_skb() once done.
- *
- * Description:
- *
- * This function delivers a message/command to the device and waits
- * for an ack to be received. The format is described in
- * linux/wimax/i2400m.h. In summary, a command/get/set is followed by an
- * ack.
- *
- * This function will not check the ack status, that's left up to the
- * caller.  Once done with the ack skb, it has to be kfree_skb()ed.
- *
- * The i2400m handles only one message at the same time, thus we need
- * the mutex to exclude other players.
- *
- * We write the message and then wait for an answer to come back. The
- * RX path intercepts control messages and handles them in
- * i2400m_rx_ctl(). Reports (notifications) are (maybe) processed
- * locally and then forwarded (as needed) to user space on the WiMAX
- * stack message pipe. Acks are saved and passed back to us through an
- * skb in i2400m->ack_skb which is ready to be given to generic
- * netlink if need be.

- *  - Initial implementation
- *
- *
- * THE PROCEDURE
- *
- * The 2400m and derived devices work in two modes: boot-mode or
- * normal mode. In boot mode we can execute only a handful of commands
- * targeted at uploading the firmware and launching it.
- *
- * The 2400m enters boot mode when it is first connected to the
- * system, when it crashes and when you ask it to reboot. There are
- * two submodes of the boot mode: signed and non-signed. Signed takes
- * firmwares signed with a certain private key, non-signed takes any
- * firmware. Normal hardware takes only signed firmware.
- *
- * On boot mode, in USB, we write to the device using the bulk out
- * endpoint and read from it in the notification endpoint.
- *
- * Upon entrance to boot mode, the device sends (preceded with a few
- * zero length packets (ZLPs) on the notification endpoint in USB) a
- * reboot barker (4 le32 words with the same value). We ack it by
- * sending the same barker to the device. The device acks with a
- * reboot ack barker (4 le32 words with value I2400M_ACK_BARKER) and
- * then is fully booted. At this point we can upload the firmware.
- *
- * Note that different iterations of the device and EEPROM
- * configurations will send different [re]boot barkers; these are
- * collected in i2400m_barker_db along with the firmware
- * characteristics they require.
- *
- * This process is accomplished by the i2400m_bootrom_init()
- * function. All the device interaction happens through the
- * i2400m_bm_cmd() [boot mode command]. Special return values will
- * indicate if the device did reset during the process.
- *
- * After this, we read the MAC address and then (if needed)
- * reinitialize the device. We need to read it ahead of time because
- * in the future, we might not upload the firmware until userspace
- * 'ifconfig up's the device.
- *
- * We can then upload the firmware file. The file is composed of a BCF
- * header (basic data, keys and signatures) and a list of write
- * commands and payloads. Optionally more BCF headers might follow the
- * main payload. We first upload the header [i2400m_dnload_init()] and
- * then pass the commands and payloads verbatim to the i2400m_bm_cmd()
- * function [i2400m_dnload_bcf()]. Then we tell the device to jump to
- * the new firmware [i2400m_dnload_finalize()].
- *
- * Once firmware is uploaded, we are good to go :)
- *
- * When we don't know in which mode we are, we first try by sending a
- * warm reset request that will take us to boot-mode. If we time out
- * waiting for a reboot barker, that means maybe we are already in
- * boot mode, so we send a reboot barker.
- *
- * COMMAND EXECUTION
- *
- * This code (and process) is single threaded; for executing commands,
- * we post a URB to the notification endpoint, post the command, wait
- * for data on the notification buffer. We don't need to worry about
- * others as we know we are the only ones in there.
- *
- * BACKEND IMPLEMENTATION
- *
- * This code is bus-generic; the bus-specific driver provides back end
- * implementations to send a boot mode command to the device and to
- * read an acknolwedgement from it (or an asynchronous notification)
- * from it.
- *
- * FIRMWARE LOADING
- *
- * Note that in some cases, we can't just load a firmware file (for
- * example, when resuming). For that, we might cache the firmware
- * file. Thus, when doing the bootstrap, if there is a cache firmware
- * file, it is used; if not, loading from disk is attempted.

- * @flags:
- *      I2400M_BRI_SOFT: a reboot barker has been seen
- *          already, so don't wait for it.
- *
- *      I2400M_BRI_NO_REBOOT: Don't send a reboot command, but wait
- *          for a reboot barker notification. This is a one shot; if
- *          the state machine needs to send a reboot command it will.
- *
- * Returns:
- *
- *     < 0 errno code on error, 0 if ok.
- *
- * Description:
- *
- * Tries hard enough to put the device in boot-mode. There are two
- * main phases to this:
- *
- * a. (1) send a reboot command and (2) get a reboot barker
- *
- * b. (1) echo/ack the reboot sending the reboot barker back and (2)
- *        getting an ack barker in return
- *
- * We want to skip (a) in some cases [soft]. The state machine is
- * horrible, but it is basically: on each phase, send what has to be
- * sent (if any), wait for the answer and act on the answer. We might
- * have to backtrack and retry, so we keep a max tries counter for
- * that.
- *
- * It sucks because we don't know ahead of time which is going to be
- * the reboot barker (the device might send different ones depending
- * on its EEPROM config) and once the device reboots and waits for the
- * echo/ack reboot barker being sent back, it doesn't understand
- * anything else. So we can be left at the point where we don't know
- * what to send to it -- cold reset and bus reset seem to have little
- * effect. So the function iterates (in this case) through all the
- * known barkers and tries them all until an ACK is
- * received. Otherwise, it gives up.
- *
- * If we get a timeout after sending a warm reset, we do it again.

- * ARCHITECTURE
- *
- * This driver listens to notifications sent from the notification

- * the data to the generic RX code (rx.c).

- * queues up in the TX FIFO (tx.c) and that will notify the driver
- * through the i2400m->bus_tx_kick() callback
- * (usb-tx.c:i2400mu_bus_tx_kick) which will send the items in the
- * FIFO queue.
- *
- * This driver, as well, implements the USB-specific ops for the generic
- * driver to be able to setup/teardown communication with the device
- * [i2400m_bus_dev_start() and i2400m_bus_dev_stop()], reseting the
- * device [i2400m_bus_reset()] and performing firmware upload
- * [i2400m_bus_bm_cmd() and i2400_bus_bm_wait_for_ack()].

- *
- * GENERAL DRIVER ARCHITECTURE
- *
- * The i2400m driver is split in the following two major parts:
- *
- *  - bus specific driver
- *  - bus generic driver (this part)
- *
- * The bus specific driver sets up stuff specific to the bus the
- * device is connected to (USB, PCI, tam-tam...non-authoritative
- * nor binding list) which is basically the device-model management
- * (probe/disconnect, etc), moving data from device to kernel and
- * back, doing the power saving details and reseting the device.
- *
- * For details on each bus-specific driver, see it's include file,
- * i2400m-BUSNAME.h
- *
- * The bus-generic functionality break up is:
- *
- *  - Firmware upload: fw.c - takes care of uploading firmware to the
- *        device. bus-specific driver just needs to provides a way to
- *        execute boot-mode commands and to reset the device.
- *
- *  - RX handling: rx.c - receives data from the bus-specific code and
- *        feeds it to the network or WiMAX stack or uses it to modify
- *        the driver state. bus-specific driver only has to receive
- *        frames and pass them to this module.
- *
- *  - TX handling: tx.c - manages the TX FIFO queue and provides means
- *        for the bus-specific TX code to pull data from the FIFO
- *        queue. bus-specific code just pulls frames from this module
- *        to sends them to the device.
- *
- *  - netdev glue: netdev.c - interface with Linux networking
- *        stack. Pass around data frames, and configure when the
- *        device is up and running or shutdown (through ifconfig up /
- *        down). Bus-generic only.
- *
- *  - control ops: control.c - implements various commands for
- *        controlling the device. bus-generic only.
- *
- *  - device model glue: driver.c - implements helpers for the
- *        device-model glue done by the bus-specific layer
- *        (setup/release the driver resources), turning the device on
- *        and off, handling the device reboots/resets and a few simple
- *        WiMAX stack ops.
- *
- * Code is also broken up in linux-glue / device-glue.
- *
- * Linux glue contains functions that deal mostly with gluing with the
- * rest of the Linux kernel.
- *
- * Device-glue are functions that deal mostly with the way the device
- * does things and talk the device's language.
- *
- * device-glue code is licensed BSD so other open source OSes can take
- * it to implement their drivers.
- *
- *
- * APIs AND HEADER FILES
- *
- * This bus generic code exports three APIs:
- *
- *  - HDI (host-device interface) definitions common to all busses
- *    (include/linux/wimax/i2400m.h); these can be also used by user
- *    space code.
- *  - internal API for the bus-generic code
- *  - external API for the bus-specific drivers
- *
- *
- * LIFE CYCLE:
- *
- * When the bus-specific driver probes, it allocates a network device
- * with enough space for it's data structue, that must contain a
- * &struct i2400m at the top.
- *
- * On probe, it needs to fill the i2400m members marked as [fill], as
- * well as i2400m->wimax_dev.net_dev and call i2400m_setup(). The
- * i2400m driver will only register with the WiMAX and network stacks;
- * the only access done to the device is to read the MAC address so we
- * can register a network device.
- *
- * The high-level call flow is:
- *
- * bus_probe()
- *   i2400m_setup()
- *     i2400m->bus_setup()
- *     boot rom initialization / read mac addr
- *     network / WiMAX stacks registration
- *     i2400m_dev_start()
- *       i2400m->bus_dev_start()
- *       i2400m_dev_initialize()
- *
- * The reverse applies for a disconnect() call:
- *
- * bus_disconnect()
- *   i2400m_release()
- *     i2400m_dev_stop()
- *       i2400m_dev_shutdown()
- *       i2400m->bus_dev_stop()
- *     network / WiMAX stack unregistration
- *     i2400m->bus_release()
- *
- * At this point, control and data communications are possible.
- *
- * While the device is up, it might reset. The bus-specific driver has
- * to catch that situation and call i2400m_dev_reset_handle() to deal
- * with it (reset the internal driver structures and go back to square
- * one).

- * struct i2400m - descriptor for an Intel 2400m
- *
- * Members marked with [fill] must be filled out/initialized before
- * calling i2400m_setup().
- *
- * Note the @bus_setup/@bus_release, @bus_dev_start/@bus_dev_release
- * call pairs are very much doing almost the same, and depending on
- * the underlying bus, some stuff has to be put in one or the
- * other. The idea of setup/release is that they setup the minimal
- * amount needed for loading firmware, where us dev_start/stop setup
- * the rest needed to do full data/control traffic.
- *
- * @bus_tx_block_size: [fill] USB imposes a 16 block size, but other
- *     busses will differ.  So we have a tx_blk_size variable that the
- *     bus layer sets to tell the engine how much of that we need.
- *
- * @bus_tx_room_min: [fill] Minimum room required while allocating
- *     TX queue's buffer space for message header. USB requires
- *     16 bytes. Refer to bus specific driver code for details.
- *
- * @bus_pl_size_max: [fill] Maximum payload size.
- *
- * @bus_setup: [optional fill] Function called by the bus-generic code
- *     [i2400m_setup()] to setup the basic bus-specific communications
- *     to the the device needed to load firmware. See LIFE CYCLE above.
- *
- *     NOTE: Doesn't need to upload the firmware, as that is taken
- *     care of by the bus-generic code.
- *
- * @bus_release: [optional fill] Function called by the bus-generic
- *     code [i2400m_release()] to shutdown the basic bus-specific
- *     communications to the the device needed to load firmware. See
- *     LIFE CYCLE above.
- *
- *     This function does not need to reset the device, just tear down
- *     all the host resources created to  handle communication with
- *     the device.
- *
- * @bus_dev_start: [optional fill] Function called by the bus-generic
- *     code [i2400m_dev_start()] to do things needed to start the
- *     device. See LIFE CYCLE above.
- *
- *     NOTE: Doesn't need to upload the firmware, as that is taken
- *     care of by the bus-generic code.
- *
- * @bus_dev_stop: [optional fill] Function called by the bus-generic
- *     code [i2400m_dev_stop()] to do things needed for stopping the
- *     device. See LIFE CYCLE above.
- *
- *     This function does not need to reset the device, just tear down
- *     all the host resources created to handle communication with
- *     the device.
- *
- * @bus_tx_kick: [fill] Function called by the bus-generic code to let
- *     the bus-specific code know that there is data available in the
- *     TX FIFO for transmission to the device.
- *
- *     This function cannot sleep.
- *
- * @bus_reset: [fill] Function called by the bus-generic code to reset
- *     the device in in various ways. Doesn't need to wait for the
- *     reset to finish.
- *
- *     If warm or cold reset fail, this function is expected to do a
- *     bus-specific reset (eg: USB reset) to get the device to a
- *     working state (even if it implies device disconecction).
- *
- *     Note the warm reset is used by the firmware uploader to
- *     reinitialize the device.
- *
- *     IMPORTANT: this is called very early in the device setup
- *     process, so it cannot rely on common infrastructure being laid
- *     out.
- *
- *     IMPORTANT: don't call reset on RT_BUS with i2400m->init_mutex
- *     held, as the .pre/.post reset handlers will deadlock.
- *
- * @bus_bm_retries: [fill] How many times shall a firmware upload /
- *     device initialization be retried? Different models of the same
- *     device might need different values, hence it is set by the
- *     bus-specific driver. Note this value is used in two places,
- *     i2400m_fw_dnload() and __i2400m_dev_start(); they won't become
- *     multiplicative (__i2400m_dev_start() calling N times
- *     i2400m_fw_dnload() and this trying N times to download the
- *     firmware), as if __i2400m_dev_start() only retries if the
- *     firmware crashed while initializing the device (not in a
- *     general case).
- *
- * @bus_bm_cmd_send: [fill] Function called to send a boot-mode
- *     command. Flags are defined in 'enum i2400m_bm_cmd_flags'. This
- *     is synchronous and has to return 0 if ok or < 0 errno code in
- *     any error condition.
- *
- * @bus_bm_wait_for_ack: [fill] Function called to wait for a
- *     boot-mode notification (that can be a response to a previously
- *     issued command or an asynchronous one). Will read until all the
- *     indicated size is read or timeout. Reading more or less data
- *     than asked for is an error condition. Return 0 if ok, < 0 errno
- *     code on error.
- *
- *     The caller to this function will check if the response is a
- *     barker that indicates the device going into reset mode.
- *
- * @bus_fw_names: [fill] a NULL-terminated array with the names of the
- *     firmware images to try loading. This is made a list so we can
- *     support backward compatibility of firmware releases (eg: if we
- *     can't find the default v1.4, we try v1.3). In general, the name
- *     should be i2400m-fw-X-VERSION.sbcf, where X is the bus name.
- *     The list is tried in order and the first one that loads is
- *     used. The fw loader will set i2400m->fw_name to point to the
- *     active firmware image.
- *
- * @bus_bm_mac_addr_impaired: [fill] Set to true if the device's MAC
- *     address provided in boot mode is kind of broken and needs to
- *     be re-read later on.
- *
- * @bus_bm_pokes_table: [fill/optional] A table of device addresses
- *     and values that will be poked at device init time to move the
- *     device to the correct state for the type of boot/firmware being
- *     used.  This table MUST be terminated with (0x000000,
- *     0x00000000) or bad things will happen.
- *
- *
- * @wimax_dev: WiMAX generic device for linkage into the kernel WiMAX
- *     stack. Due to the way a net_device is allocated, we need to
- *     force this to be the first field so that we can get from
- *     netdev_priv() the right pointer.
- *
- * @updown: the device is up and ready for transmitting control and
- *     data packets. This implies @ready (communication infrastructure
- *     with the device is ready) and the device's firmware has been
- *     loaded and the device initialized.
- *
- *     Write to it only inside a i2400m->init_mutex protected area
- *     followed with a wmb(); rmb() before accesing (unless locked
- *     inside i2400m->init_mutex). Read access can be loose like that
- *     [just using rmb()] because the paths that use this also do
- *     other error checks later on.
- *
- * @ready: Communication infrastructure with the device is ready, data
- *     frames can start to be passed around (this is lighter than
- *     using the WiMAX state for certain hot paths).
- *
- *     Write to it only inside a i2400m->init_mutex protected area
- *     followed with a wmb(); rmb() before accesing (unless locked
- *     inside i2400m->init_mutex). Read access can be loose like that
- *     [just using rmb()] because the paths that use this also do
- *     other error checks later on.
- *
- * @rx_reorder: 1 if RX reordering is enabled; this can only be
- *     set at probe time.
- *
- * @state: device's state (as reported by it)
- *
- * @state_wq: waitqueue that is woken up whenever the state changes
- *
- * @tx_lock: spinlock to protect TX members
- *
- * @tx_buf: FIFO buffer for TX; we queue data here
- *
- * @tx_in: FIFO index for incoming data. Note this doesn't wrap around
- *     and it is always greater than @tx_out.
- *
- * @tx_out: FIFO index for outgoing data
- *
- * @tx_msg: current TX message that is active in the FIFO for
- *     appending payloads.
- *
- * @tx_sequence: current sequence number for TX messages from the
- *     device to the host.
- *
- * @tx_msg_size: size of the current message being transmitted by the
- *     bus-specific code.
- *
- * @tx_pl_num: total number of payloads sent
- *
- * @tx_pl_max: maximum number of payloads sent in a TX message
- *
- * @tx_pl_min: minimum number of payloads sent in a TX message
- *
- * @tx_num: number of TX messages sent
- *
- * @tx_size_acc: number of bytes in all TX messages sent
- *     (this is different to net_dev's statistics as it also counts
- *     control messages).
- *
- * @tx_size_min: smallest TX message sent.
- *
- * @tx_size_max: biggest TX message sent.
- *
- * @rx_lock: spinlock to protect RX members and rx_roq_refcount.
- *
- * @rx_pl_num: total number of payloads received
- *
- * @rx_pl_max: maximum number of payloads received in a RX message
- *
- * @rx_pl_min: minimum number of payloads received in a RX message
- *
- * @rx_num: number of RX messages received
- *
- * @rx_size_acc: number of bytes in all RX messages received
- *     (this is different to net_dev's statistics as it also counts
- *     control messages).
- *
- * @rx_size_min: smallest RX message received.
- *
- * @rx_size_max: buggest RX message received.
- *
- * @rx_roq: RX ReOrder queues. (fw >= v1.4) When packets are received
- *     out of order, the device will ask the driver to hold certain
- *     packets until the ones that are received out of order can be
- *     delivered. Then the driver can release them to the host. See
- *     drivers/net/i2400m/rx.c for details.
- *
- * @rx_roq_refcount: refcount rx_roq. This refcounts any access to
- *     rx_roq thus preventing rx_roq being destroyed when rx_roq
- *     is being accessed. rx_roq_refcount is protected by rx_lock.
- *
- * @rx_reports: reports received from the device that couldn't be
- *     processed because the driver wasn't still ready; when ready,
- *     they are pulled from here and chewed.
- *
- * @rx_reports_ws: Work struct used to kick a scan of the RX reports
- *     list and to process each.
- *
- * @src_mac_addr: MAC address used to make ethernet packets be coming
- *     from. This is generated at i2400m_setup() time and used during
- *     the life cycle of the instance. See i2400m_fake_eth_header().
- *
- * @init_mutex: Mutex used for serializing the device bringup
- *     sequence; this way if the device reboots in the middle, we
- *     don't try to do a bringup again while we are tearing down the
- *     one that failed.
- *
- *     Can't reuse @msg_mutex because from within the bringup sequence
- *     we need to send messages to the device and thus use @msg_mutex.
- *
- * @msg_mutex: mutex used to send control commands to the device (we
- *     only allow one at a time, per host-device interface design).
- *
- * @msg_completion: used to wait for an ack to a control command sent
- *     to the device.
- *
- * @ack_skb: used to store the actual ack to a control command if the
- *     reception of the command was successful. Otherwise, a ERR_PTR()
- *     errno code that indicates what failed with the ack reception.
- *
- *     Only valid after @msg_completion is woken up. Only updateable
- *     if @msg_completion is armed. Only touched by
- *     i2400m_msg_to_dev().
- *
- *     Protected by @rx_lock. In theory the command execution flow is
- *     sequential, but in case the device sends an out-of-phase or
- *     very delayed response, we need to avoid it trampling current
- *     execution.
- *
- * @bm_cmd_buf: boot mode command buffer for composing firmware upload
- *     commands.
- *
- *     USB can't r/w to stack, vmalloc, etc...as well, we end up
- *     having to alloc/free a lot to compose commands, so we use these
- *     for stagging and not having to realloc all the time.
- *
- *     This assumes the code always runs serialized. Only one thread
- *     can call i2400m_bm_cmd() at the same time.
- *
- * @bm_ack_buf: boot mode acknoledge buffer for staging reception of
- *     responses to commands.
- *
- *     See @bm_cmd_buf.
- *
- * @work_queue: work queue for processing device reports. This
- *     workqueue cannot be used for processing TX or RX to the device,
- *     as from it we'll process device reports, which might require
- *     further communication with the device.
- *
- * @debugfs_dentry: hookup for debugfs files.
- *     These have to be in a separate directory, a child of
- *     (wimax_dev->debugfs_dentry) so they can be removed when the
- *     module unloads, as we don't keep each dentry.
- *
- * @fw_name: name of the firmware image that is currently being used.
- *
- * @fw_version: version of the firmware interface, Major.minor,
- *     encoded in the high word and low word (major << 16 | minor).
- *
- * @fw_hdrs: NULL terminated array of pointers to the firmware
- *     headers. This is only available during firmware load time.
- *
- * @fw_cached: Used to cache firmware when the system goes to
- *     suspend/standby/hibernation (as on resume we can't read it). If
- *     NULL, no firmware was cached, read it. If ~0, you can't read
- *     any firmware files (the system still didn't come out of suspend
- *     and failed to cache one), so abort; otherwise, a valid cached
- *     firmware to be used. Access to this variable is protected by
- *     the spinlock i2400m->rx_lock.
- *
- * @barker: barker type that the device uses; this is initialized by
- *     i2400m_is_boot_barker() the first time it is called. Then it
- *     won't change during the life cycle of the device and every time
- *     a boot barker is received, it is just verified for it being the
- *     same.
- *
- * @pm_notifier: used to register for PM events
- *
- * @bus_reset_retries: counter for the number of bus resets attempted for
- *	this boot. It's not for tracking the number of bus resets during
- *	the whole driver life cycle (from insmod to rmmod) but for the
- *	number of dev_start() executed until dev_start() returns a success
- *	(ie: a good boot means a dev_stop() followed by a successful
- *	dev_start()). dev_reset_handler() increments this counter whenever
- *	it is triggering a bus reset. It checks this counter to decide if a
- *	subsequent bus reset should be retried. dev_reset_handler() retries
- *	the bus reset until dev_start() succeeds or the counter reaches
- *	I2400M_BUS_RESET_RETRIES. The counter is cleared to 0 in
- *	dev_reset_handle() when dev_start() returns a success,
- *	ie: a successul boot is completed.
- *
- * @alive: flag to denote if the device *should* be alive. This flag is
- *	everything like @updown (see doc for @updown) except reflecting
- *	the device state *we expect* rather than the actual state as denoted
- *	by @updown. It is set 1 whenever @updown is set 1 in dev_start().
- *	Then the device is expected to be alive all the time
- *	(i2400m->alive remains 1) until the driver is removed. Therefore
- *	all the device reboot events detected can be still handled properly
- *	by either dev_reset_handle() or .pre_reset/.post_reset as long as
- *	the driver presents. It is set 0 along with @updown in dev_stop().
- *
- * @error_recovery: flag to denote if we are ready to take an error recovery.
- *	0 for ready to take an error recovery; 1 for not ready. It is
- *	initialized to 1 while probe() since we don't tend to take any error
- *	recovery during probe(). It is decremented by 1 whenever dev_start()
- *	succeeds to indicate we are ready to take error recovery from now on.
- *	It is checked every time we wanna schedule an error recovery. If an
- *	error recovery is already in place (error_recovery was set 1), we
- *	should not schedule another one until the last one is done.

- *  - Initial implementation
- *
- *
- * This header defines the data structures and constants used to
- * communicate with the device.
- *
- * BOOTMODE/BOOTROM/FIRMWARE UPLOAD PROTOCOL
- *
- * The firmware upload protocol is quite simple and only requires a
- * handful of commands. See drivers/net/wimax/i2400m/fw.c for more
- * details.
- *
- * The BCF data structure is for the firmware file header.
- *
- *
- * THE DATA / CONTROL PROTOCOL
- *
- * This is the normal protocol spoken with the device once the
- * firmware is uploaded. It transports data payloads and control
- * messages back and forth.
- *
- * It consists 'messages' that pack one or more payloads each. The
- * format is described in detail in drivers/net/wimax/i2400m/rx.c and
- * tx.c.
- *
- *
- * THE L3L4 PROTOCOL
- *
- * The term L3L4 refers to Layer 3 (the device), Layer 4 (the
- * driver/host software).
- *
- * This is the control protocol used by the host to control the i2400m
- * device (scan, connect, disconnect...). This is sent to / received
- * as control frames. These frames consist of a header and zero or
- * more TLVs with information. We call each control frame a "message".
- *
- * Each message is composed of:
- *
- * HEADER
- * [TLV0 + PAYLOAD0]
- * [TLV1 + PAYLOAD1]
- * [...]
- * [TLVN + PAYLOADN]
- *
- * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are
- * defined by a TLV structure (Type Length Value) which is a 'header'
- * (struct i2400m_tlv_hdr) and then the payload.
- *
- * All integers are represented as Little Endian.
- *
- * - REQUESTS AND EVENTS
- *
- * The requests can be clasified as follows:
- *
- *   COMMAND:  implies a request from the host to the device requesting
- *             an action being performed. The device will reply with a
- *             message (with the same type as the command), status and
- *             no (TLV) payload. Execution of a command might cause
- *             events (of different type) to be sent later on as
- *             device's state changes.
- *
- *   GET/SET:  similar to COMMAND, but will not cause other
- *             EVENTs. The reply, in the case of GET, will contain
- *             TLVs with the requested information.
- *
- *   EVENT:    asynchronous messages sent from the device, maybe as a
- *             consequence of previous COMMANDs but disassociated from
- *             them.
- *
- * Only one request might be pending at the same time (ie: don't
- * parallelize nor post another GET request before the previous
- * COMMAND has been acknowledged with it's corresponding reply by the
- * device).
- *
- * The different requests and their formats are described below:
- *
- *  I2400M_MT_*   Message types
- *  I2400M_MS_*   Message status (for replies, events)
- *  i2400m_tlv_*  TLVs
- *
- * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the
- * operation.

- * This implements an ethernet device for the i2400m.
- *
- * We fake being an ethernet device to simplify the support from user
- * space and from the other side. The world is (sadly) configured to
- * take in only Ethernet devices...
- *
- * Because of this, when using firmwares <= v1.3, there is an
- * copy-each-rxed-packet overhead on the RX path. Each IP packet has
- * to be reallocated to add an ethernet header (as there is no space
- * in what we get from the device). This is a known drawback and
- * firmwares >= 1.4 add header space that can be used to insert the
- * ethernet header without having to reallocate and copy.
- *
- * TX error handling is tricky; because we have to FIFO/queue the
- * buffers for transmission (as the hardware likes it aggregated), we
- * just give the skb to the TX subsystem and by the time it is
- * transmitted, we have long forgotten about it. So we just don't care
- * too much about it.
- *
- * Note that when the device is in idle mode with the basestation, we
- * need to negotiate coming back up online. That involves negotiation
- * and possible user space interaction. Thus, we defer to a workqueue
- * to do all that. By default, we only queue a single packet and drop
- * the rest, as potentially the time to go back from idle to normal is
- * long.

- *  - Use skb_clone(), break up processing in chunks
- *  - Split transport/device specific
- *  - Make buffer size dynamic to exert less memory pressure
- *  - RX reorder support
- *
- * This handles the RX path.
- *
- * We receive an RX message from the bus-specific driver, which
- * contains one or more payloads that have potentially different
- * destinataries (data or control paths).
- *
- * So we just take that payload from the transport specific code in
- * the form of an skb, break it up in chunks (a cloned skb each in the
- * case of network packets) and pass it to netdev or to the
- * command/ack handler (and from there to the WiMAX stack).
- *
- * PROTOCOL FORMAT
- *
- * The format of the buffer is:
- *
- * HEADER                      (struct i2400m_msg_hdr)
- * PAYLOAD DESCRIPTOR 0        (struct i2400m_pld)
- * PAYLOAD DESCRIPTOR 1
- * ...
- * PAYLOAD DESCRIPTOR N
- * PAYLOAD 0                   (raw bytes)
- * PAYLOAD 1
- * ...
- * PAYLOAD N
- *
- * See tx.c for a deeper description on alignment requirements and
- * other fun facts of it.
- *
- * DATA PACKETS
- *
- * In firmwares <= v1.3, data packets have no header for RX, but they
- * do for TX (currently unused).
- *
- * In firmware >= 1.4, RX packets have an extended header (16
- * bytes). This header conveys information for management of host
- * reordering of packets (the device offloads storage of the packets
- * for reordering to the host). Read below for more information.
- *
- * The header is used as dummy space to emulate an ethernet header and
- * thus be able to act as an ethernet device without having to reallocate.
- *
- * DATA RX REORDERING
- *
- * Starting in firmware v1.4, the device can deliver packets for
- * delivery with special reordering information; this allows it to
- * more effectively do packet management when some frames were lost in
- * the radio traffic.
- *
- * Thus, for RX packets that come out of order, the device gives the
- * driver enough information to queue them properly and then at some
- * point, the signal to deliver the whole (or part) of the queued
- * packets to the networking stack. There are 16 such queues.
- *
- * This only happens when a packet comes in with the "need reorder"
- * flag set in the RX header. When such bit is set, the following
- * operations might be indicated:
- *
- *  - reset queue: send all queued packets to the OS
- *
- *  - queue: queue a packet
- *
- *  - update ws: update the queue's window start and deliver queued
- *    packets that meet the criteria
- *
- *  - queue & update ws: queue a packet, update the window start and
- *    deliver queued packets that meet the criteria
- *
- * (delivery criteria: the packet's [normalized] sequence number is
- * lower than the new [normalized] window start).
- *
- * See the i2400m_roq_*() functions for details.

- *  - Initial implementation
- *
- * Intel Corporation <linux-wimax@intel.com>
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *  - Rewritten to use a single FIFO to lower the memory allocation
- *    pressure and optimize cache hits when copying to the queue, as
- *    well as splitting out bus-specific code.
- *
- *
- * Implements data transmission to the device; this is done through a
- * software FIFO, as data/control frames can be coalesced (while the
- * device is reading the previous tx transaction, others accumulate).
- *
- * A FIFO is used because at the end it is resource-cheaper that trying
- * to implement scatter/gather over USB. As well, most traffic is going
- * to be download (vs upload).
- *
- * The format for sending/receiving data to/from the i2400m is
- * described in detail in rx.c:PROTOCOL FORMAT. In here we implement
- * the transmission of that. This is split between a bus-independent
- * part that just prepares everything and a bus-specific part that
- * does the actual transmission over the bus to the device (in the
- * bus-specific driver).
- *
- *
- * The general format of a device-host transaction is MSG-HDR, PLD1,
- * PLD2...PLDN, PL1, PL2,...PLN, PADDING.
- *
- * Because we need the send payload descriptors and then payloads and
- * because it is kind of expensive to do scatterlists in USB (one URB
- * per node), it becomes cheaper to append all the data to a FIFO
- * (copying to a FIFO potentially in cache is cheaper).
- *
- * Then the bus-specific code takes the parts of that FIFO that are
- * written and passes them to the device.
- *
- * So the concepts to keep in mind there are:
- *
- * We use a FIFO to queue the data in a linear buffer. We first append
- * a MSG-HDR, space for I2400M_TX_PLD_MAX payload descriptors and then
- * go appending payloads until we run out of space or of payload
- * descriptors. Then we append padding to make the whole transaction a
- * multiple of i2400m->bus_tx_block_size (as defined by the bus layer).
- *
- * - A TX message: a combination of a message header, payload
- *   descriptors and payloads.
- *
- *     Open: it is marked as active (i2400m->tx_msg is valid) and we
- *       can keep adding payloads to it.
- *
- *     Closed: we are not appending more payloads to this TX message
- *       (exahusted space in the queue, too many payloads or
- *       whichever).  We have appended padding so the whole message
- *       length is aligned to i2400m->bus_tx_block_size (as set by the
- *       bus/transport layer).
- *
- * - Most of the time we keep a TX message open to which we append
- *   payloads.
- *
- * - If we are going to append and there is no more space (we are at
- *   the end of the FIFO), we close the message, mark the rest of the
- *   FIFO space unusable (skip_tail), create a new message at the
- *   beginning of the FIFO (if there is space) and append the message
- *   there.
- *
- *   This is because we need to give linear TX messages to the bus
- *   engine. So we don't write a message to the remaining FIFO space
- *   until the tail and continue at the head of it.
- *
- * - We overload one of the fields in the message header to use it as
- *   'size' of the TX message, so we can iterate over them. It also
- *   contains a flag that indicates if we have to skip it or not.
- *   When we send the buffer, we update that to its real on-the-wire
- *   value.
- *
- * - The MSG-HDR PLD1...PLD2 stuff has to be a size multiple of 16.
- *
- *   It follows that if MSG-HDR says we have N messages, the whole
- *   header + descriptors is 16 + 4*N; for those to be a multiple of
- *   16, it follows that N can be 4, 8, 12, ... (32, 48, 64, 80...
- *   bytes).
- *
- *   So if we have only 1 payload, we have to submit a header that in
- *   all truth has space for 4.
- *
- *   The implication is that we reserve space for 12 (64 bytes); but
- *   if we fill up only (eg) 2, our header becomes 32 bytes only. So
- *   the TX engine has to shift those 32 bytes of msg header and 2
- *   payloads and padding so that right after it the payloads start
- *   and the TX engine has to know about that.
- *
- *   It is cheaper to move the header up than the whole payloads down.
- *
- *   We do this in i2400m_tx_close(). See 'i2400m_msg_hdr->offset'.
- *
- * - Each payload has to be size-padded to 16 bytes; before appending
- *   it, we just do it.
- *
- * - The whole message has to be padded to i2400m->bus_tx_block_size;
- *   we do this at close time. Thus, when reserving space for the
- *   payload, we always make sure there is also free space for this
- *   padding that sooner or later will happen.
- *
- * When we append a message, we tell the bus specific code to kick in
- * TXs. It will TX (in parallel) until the buffer is exhausted--hence
- * the lockin we do. The TX code will only send a TX message at the
- * time (which remember, might contain more than one payload). Of
- * course, when the bus-specific driver attempts to TX a message that
- * is still open, it gets closed first.
- *
- * Gee, this is messy; well a picture. In the example below we have a
- * partially full FIFO, with a closed message ready to be delivered
- * (with a moved message header to make sure it is size-aligned to
- * 16), TAIL room that was unusable (and thus is marked with a message
- * header that says 'skip this') and at the head of the buffer, an
- * incomplete message with a couple of payloads.

- *
- * This corner case is avoided by using a try_head boolean,

- *

- *
- * This file implements only the USB specifics. It boils down to how

- *
- * This code (and process) is single threaded. It assumes it is the
- * only thread poking around (guaranteed by fw.c).
- *
- * COMMAND EXECUTION
- *
- * A write URB is posted with the buffer to the bulk output endpoint.
- *
- * ACK RECEPTION
- *
- * We just post a URB to the notification endpoint and wait for
- * data. We repeat until we get all the data we expect (as indicated
- * by the call from the bus generic code).
- *
- * The data is not read from the bulk in endpoint for boot mode.

- *  - Use skb_clone(), break up processing in chunks
- *  - Split transport/device specific
- *  - Make buffer size dynamic to exert less memory pressure
- *
- *
- * This handles the RX path on USB.
- *
- * When a notification is received that says 'there is RX data ready',
- * we call i2400mu_rx_kick(); that wakes up the RX kthread, which
- * reads a buffer from USB and passes it to i2400m_rx() in the generic
- * handling code. The RX buffer has an specific format that is
- * described in rx.c.
- *
- * We use a kernel thread in a loop because:
- *
- *  - we want to be able to call the USB power management get/put
- *    functions (blocking) before each transaction.
- *
- *  - We might get a lot of notifications and we don't want to submit
- *    a zillion reads; by serializing, we are throttling.
- *
- *  - RX data processing can get heavy enough so that it is not
- *    appropriate for doing it in the USB callback; thus we run it in a
- *    process context.
- *
- * We provide a read buffer of an arbitrary size (short of a page); if
- * the callback reports -EOVERFLOW, it means it was too small, so we
- * just double the size and retry (being careful to append, as
- * sometimes the device provided some data). Every now and then we
- * check if the average packet size is smaller than the current packet
- * size and if so, we halve it. At the end, the size of the
- * preallocated buffer should be following the average received
- * transaction size, adapting dynamically to it.
- *
- * ROADMAP

- * Dynamic RX size
- *
- * We can't let the rx_size be a multiple of 512 bytes (the RX

- * about to send (for example) X bytes and we only post a buffer to

- * So on growing or shrinking, if it is a multiple of the
- * maxpacketsize, we remove some (instead of incresing some, so in a

- * Note we also need a hook for this on i2400mu_rx() -- when we do the
- * first read, we are sure we won't hit this spot because
- * i240mm->rx_size has been set properly. However, if we have to
- * double because of -EOVERFLOW, when we launch the read to get the

- * just a single WiMAX adapter.
- *
- * We put all the WiMAX devices in the system in a linked list and

- * Don't #include this file directly, read on!
- *
- * EXECUTING DEBUGGING ACTIONS OR NOT
- *
- * The main thing this framework provides is decission power to take a
- * debug action (like printing a message) if the current debug level
- * allows it.
- *
- * The decission power is at two levels: at compile-time (what does
- * not make it is compiled out) and at run-time. The run-time
- * selection is done per-submodule (as they are declared by the user
- * of the framework).
- *
- * A call to d_test(L) (L being the target debug level) returns true
- * if the action should be taken because the current debug levels
- * allow it (both compile and run time).
- *
- * It follows that a call to d_test() that can be determined to be
- * always false at compile time will get the code depending on it
- * compiled out by optimization.
- *
- * DEBUG LEVELS
- *
- * It is up to the caller to define how much a debugging level is.
- *
- * Convention sets 0 as "no debug" (so an action marked as debug level 0
- * will always be taken). The increasing debug levels are used for
- * increased verbosity.
- *
- * USAGE
- *
- * Group the code in modules and submodules inside each module [which
- * in most cases maps to Linux modules and .c files that compose
- * those].
- *
- * For each module, there is:
- *
- *  - a MODULENAME (single word, legal C identifier)
- *
- *  - a debug-levels.h header file that declares the list of
- *    submodules and that is included by all .c files that use
- *    the debugging tools. The file name can be anything.
- *
- *  - some (optional) .c code to manipulate the runtime debug levels
- *    through debugfs.
- *
- * The debug-levels.h file would look like:
- *
- *     #ifndef __debug_levels__h__
- *     #define __debug_levels__h__
- *
- *     #define D_MODULENAME modulename
- *     #define D_MASTER 10
- *
- *     #include "linux-wimax-debug.h"
- *
- *     enum d_module {
- *             D_SUBMODULE_DECLARE(submodule_1),
- *             D_SUBMODULE_DECLARE(submodule_2),
- *             ...
- *             D_SUBMODULE_DECLARE(submodule_N)
- *     };
- *
- *     #endif
- *
- * D_MASTER is the maximum compile-time debug level; any debug actions
- * above this will be out. D_MODULENAME is the module name (legal C
- * identifier), which has to be unique for each module (to avoid
- * namespace collisions during linkage). Note those #defines need to
- * be done before #including debug.h
- *
- * We declare N different submodules whose debug level can be
- * independently controlled during runtime.
- *
- * In a .c file of the module (and only in one of them), define the
- * following code:
- *
- *     struct d_level D_LEVEL[] = {
- *             D_SUBMODULE_DEFINE(submodule_1),
- *             D_SUBMODULE_DEFINE(submodule_2),
- *             ...
- *             D_SUBMODULE_DEFINE(submodule_N),
- *     };
- *     size_t D_LEVEL_SIZE = ARRAY_SIZE(D_LEVEL);
- *
- * Externs for d_level_MODULENAME and d_level_size_MODULENAME are used
- * and declared in this file using the D_LEVEL and D_LEVEL_SIZE macros
- * #defined also in this file.
- *
- * To manipulate from user space the levels, create a debugfs dentry
- * and then register each submodule with:
- *
- *     d_level_register_debugfs("PREFIX_", submodule_X, parent);
- *
- * Where PREFIX_ is a name of your chosing. This will create debugfs
- * file with a single numeric value that can be use to tweak it. To
- * remove the entires, just use debugfs_remove_recursive() on 'parent'.
- *
- * NOTE: remember that even if this will show attached to some
- *     particular instance of a device, the settings are *global*.
- *
- * On each submodule (for example, .c files), the debug infrastructure
- * should be included like this:
- *
- *     #define D_SUBMODULE submodule_x     // matches one in debug-levels.h
- *     #include "debug-levels.h"
- *
- * after #including all your include files.
- *
- * Now you can use the d_*() macros below [d_test(), d_fnstart(),
- * d_fnend(), d_printf(), d_dump()].
- *
- * If their debug level is greater than D_MASTER, they will be
- * compiled out.
- *
- * If their debug level is lower or equal than D_MASTER but greater
- * than the current debug level of their submodule, they'll be
- * ignored.
- *
- * Otherwise, the action will be performed.

-/**
- * enum wimax_st - The different states of a WiMAX device
- * @__WIMAX_ST_NULL: The device structure has been allocated and zeroed,
- *     but still wimax_dev_add() hasn't been called. There is no state.
- *
- * @WIMAX_ST_DOWN: The device has been registered with the WiMAX and
- *     networking stacks, but it is not initialized (normally that is
- *     done with 'ifconfig DEV up' [or equivalent], which can upload
- *     firmware and enable communications with the device).
- *     In this state, the device is powered down and using as less
- *     power as possible.
- *     This state is the default after a call to wimax_dev_add(). It
- *     is ok to have drivers move directly to %WIMAX_ST_UNINITIALIZED
- *     or %WIMAX_ST_RADIO_OFF in _probe() after the call to
- *     wimax_dev_add().
- *     It is recommended that the driver leaves this state when
- *     calling 'ifconfig DEV up' and enters it back on 'ifconfig DEV
- *     down'.
- *
- * @__WIMAX_ST_QUIESCING: The device is being torn down, so no API
- *     operations are allowed to proceed except the ones needed to
- *     complete the device clean up process.
- *
- * @WIMAX_ST_UNINITIALIZED: [optional] Communication with the device
- *     is setup, but the device still requires some configuration
- *     before being operational.
- *     Some WiMAX API calls might work.
- *
- * @WIMAX_ST_RADIO_OFF: The device is fully up; radio is off (wether
- *     by hardware or software switches).
- *     It is recommended to always leave the device in this state
- *     after initialization.
- *
- * @WIMAX_ST_READY: The device is fully up and radio is on.
- *
- * @WIMAX_ST_SCANNING: [optional] The device has been instructed to
- *     scan. In this state, the device cannot be actively connected to
- *     a network.
- *
- * @WIMAX_ST_CONNECTING: The device is connecting to a network. This
- *     state exists because in some devices, the connect process can
- *     include a number of negotiations between user space, kernel
- *     space and the device. User space needs to know what the device
- *     is doing. If the connect sequence in a device is atomic and
- *     fast, the device can transition directly to CONNECTED
- *
- * @WIMAX_ST_CONNECTED: The device is connected to a network.
- *
- * @__WIMAX_ST_INVALID: This is an invalid state used to mark the
- *     maximum numeric value of states.
- *
- * Description:
- *
- * Transitions from one state to another one are atomic and can only
- * be caused in kernel space with wimax_state_change(). To read the
- * state, use wimax_state_get().
- *
- * States starting with __ are internal and shall not be used or
- * referred to by drivers or userspace. They look ugly, but that's the
- * point -- if any use is made non-internal to the stack, it is easier
- * to catch on review.
- *
- * All API operations [with well defined exceptions] will take the
- * device mutex before starting and then check the state. If the state
- * is %__WIMAX_ST_NULL, %WIMAX_ST_DOWN, %WIMAX_ST_UNINITIALIZED or
- * %__WIMAX_ST_QUIESCING, it will drop the lock and quit with
- * -%EINVAL, -%ENOMEDIUM, -%ENOTCONN or -%ESHUTDOWN.
- *
- * The order of the definitions is important, so we can do numerical
- * comparisons (eg: < %WIMAX_ST_RADIO_OFF means the device is not ready
- * to operate).
- */
-/*
- * The allowed state transitions are described in the table below

- * Linux WiMAX
- * Kernel space API for accessing WiMAX devices
- *
- * Copyright (C) 2007-2008 Intel Corporation <linux-wimax@intel.com>
- * Inaky Perez-Gonzalez <inaky.perez-gonzalez@intel.com>
- *
- * The WiMAX stack provides an API for controlling and managing the
- * system's WiMAX devices. This API affects the control plane; the
- * data plane is accessed via the network stack (netdev).
- *
- * Parts of the WiMAX stack API and notifications are exported to
- * user space via Generic Netlink. In user space, libwimax (part of
- * the wimax-tools package) provides a shim layer for accessing those
- * calls.
- *
- * The API is standarized for all WiMAX devices and different drivers
- * implement the backend support for it. However, device-specific
- * messaging pipes are provided that can be used to issue commands and
- * receive notifications in free form.
- *
- * Currently the messaging pipes are the only means of control as it
- * is not known (due to the lack of more devices in the market) what
- * will be a good abstraction layer. Expect this to change as more
- * devices show in the market. This API is designed to be growable in
- * order to address this problem.
- *
- * USAGE
- *
- * Embed a `struct wimax_dev` at the beginning of the device's
- * private structure, initialize and register it. For details, see
- * `struct wimax_dev`s documentation.
- *
- * Once this is done, wimax-tools's libwimaxll can be used to
- * communicate with the driver from user space. You user space
- * application does not have to forcibily use libwimaxll and can talk
- * the generic netlink protocol directly if desired.
- *
- * Remember this is a very low level API that will to provide all of
- * WiMAX features. Other daemons and services running in user space
- * are the expected clients of it. They offer a higher level API that
- * applications should use (an example of this is the Intel's WiMAX
- * Network Service for the i2400m).
- *
- * DESIGN
- *
- * Although not set on final stone, this very basic interface is
- * mostly completed. Remember this is meant to grow as new common
- * operations are decided upon. New operations will be added to the
- * interface, intent being on keeping backwards compatibility as much
- * as possible.
- *
- * This layer implements a set of calls to control a WiMAX device,
- * exposing a frontend to the rest of the kernel and user space (via
- * generic netlink) and a backend implementation in the driver through
- * function pointers.
- *
- * WiMAX devices have a state, and a kernel-only API allows the
- * drivers to manipulate that state. State transitions are atomic, and
- * only some of them are allowed (see `enum wimax_st`).
- *
- * Most API calls will set the state automatically; in most cases
- * drivers have to only report state changes due to external
- * conditions.
- *
- * All API operations are 'atomic', serialized through a mutex in the
- * `struct wimax_dev`.
- *
- * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK
- *
- * The API is exported to user space using generic netlink (other
- * methods can be added as needed).
- *
- * There is a Generic Netlink Family named "WiMAX", where interfaces
- * supporting the WiMAX interface receive commands and broadcast their
- * signals over a multicast group named "msg".
- *
- * Mapping to the source/destination interface is done by an interface
- * index attribute.
- *
- * For user-to-kernel traffic (commands) we use a function call
- * marshalling mechanism, where a message X with attributes A, B, C
- * sent from user space to kernel space means executing the WiMAX API
- * call wimax_X(A, B, C), sending the results back as a message.
- *
- * Kernel-to-user (notifications or signals) communication is sent
- * over multicast groups. This allows to have multiple applications
- * monitoring them.
- *
- * Each command/signal gets assigned it's own attribute policy. This
- * way the validator will verify that all the attributes in there are
- * only the ones that should be for each command/signal. Thing of an
- * attribute mapping to a type+argumentname for each command/signal.
- *
- * If we had a single policy for *all* commands/signals, after running
- * the validator we'd have to check "does this attribute belong in
- * here"?  for each one. It can be done manually, but it's just easier
- * to have the validator do that job with multiple policies. As well,
- * it makes it easier to later expand each command/signal signature
- * without affecting others and keeping the namespace more or less
- * sane. Not that it is too complicated, but it makes it even easier.
- *
- * No state information is maintained in the kernel for each user
- * space connection (the connection is stateless).
- *
- * TESTING FOR THE INTERFACE AND VERSIONING
- *
- * If network interface X is a WiMAX device, there will be a Generic
- * Netlink family named "WiMAX X" and the device will present a
- * "wimax" directory in it's network sysfs directory
- * (/sys/class/net/DEVICE/wimax) [used by HAL].
- *
- * The inexistence of any of these means the device does not support
- * this WiMAX API.
- *
- * By querying the generic netlink controller, versioning information
- * and the multicast groups available can be found. Applications using
- * the interface can either rely on that or use the generic netlink
- * controller to figure out which generic netlink commands/signals are
- * supported.
- *
- * NOTE: this versioning is a last resort to avoid hard
- *    incompatibilities. It is the intention of the design of this
- *    stack not to introduce backward incompatible changes.
- *
- * The version code has to fit in one byte (restrictions imposed by
- * generic netlink); we use `version / 10` for the major version and
- * `version % 10` for the minor. This gives 9 minors for each major
- * and 25 majors.
- *
- * The version change protocol is as follow:
- *
- * - Major versions: needs to be increased if an existing message/API
- *   call is changed or removed. Doesn't need to be changed if a new
- *   message is added.
- *
- * - Minor version: needs to be increased if new messages/API calls are
- *   being added or some other consideration that doesn't impact the
- *   user-kernel interface too much (like some kind of bug fix) and
- *   that is kind of left up in the air to common sense.
- *
- * User space code should not try to work if the major version it was
- * compiled for differs from what the kernel offers. As well, if the
- * minor version of the kernel interface is lower than the one user
- * space is expecting (the one it was compiled for), the kernel
- * might be missing API calls; user space shall be ready to handle
- * said condition. Use the generic netlink controller operations to
- * find which ones are supported and which not.
- *
- * libwimaxll:wimaxll_open() takes care of checking versions.
- *
- * THE OPERATIONS:
- *
- * Each operation is defined in its on file (drivers/net/wimax/op-*.c)
- * for clarity. The parts needed for an operation are:
- *
- *  - a function pointer in `struct wimax_dev`: optional, as the
- *    operation might be implemented by the stack and not by the
- *    driver.
- *
- *    All function pointers are named wimax_dev->op_*(), and drivers
- *    must implement them except where noted otherwise.
- *
- *  - When exported to user space, a `struct nla_policy` to define the
- *    attributes of the generic netlink command and a `struct genl_ops`
- *    to define the operation.
- *
- * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>)
- * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in
- * include/linux/wimax.h; this file is intended to be cloned by user
- * space to gain access to those declarations.
- *
- * A few caveats to remember:
- *
- *  - Need to define attribute numbers starting in 1; otherwise it
- *    fails.
- *
- *  - the `struct genl_family` requires a maximum attribute id; when
- *    defining the `struct nla_policy` for each message, it has to have
- *    an array size of WIMAX_GNL_ATTR_MAX+1.
- *
- * The op_*() function pointers will not be called if the wimax_dev is
- * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is:
- *
- * - op_reset: can be called at any time after wimax_dev_add() has
- *   been called.
- *
- * THE PIPE INTERFACE:
- *
- * This interface is kept intentionally simple. The driver can send
- * and receive free-form messages to/from user space through a
- * pipe. See drivers/net/wimax/op-msg.c for details.
- *
- * The kernel-to-user messages are sent with
- * wimax_msg(). user-to-kernel messages are delivered via
- * wimax_dev->op_msg_from_user().
- *
- * RFKILL:
- *
- * RFKILL support is built into the wimax_dev layer; the driver just
- * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in
- * the hardware or software RF kill switches. When the stack wants to
- * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(),
- * which the driver implements.
- *
- * User space can set the software RF Kill switch by calling
- * wimax_rfkill().
- *
- * The code for now only supports devices that don't require polling;
- * If the device needs to be polled, create a self-rearming delayed
- * work struct for polling or look into adding polled support to the
- * WiMAX stack.
- *
- * When initializing the hardware (_probe), after calling
- * wimax_dev_add(), query the device for it's RF Kill switches status
- * and feed it back to the WiMAX stack using
- * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always
- * report it as ON.
- *
- * NOTE: the wimax stack uses an inverted terminology to that of the
- * RFKILL subsystem:
- *
- *  - ON: radio is ON, RFKILL is DISABLED or OFF.
- *  - OFF: radio is OFF, RFKILL is ENABLED or ON.
- *
- * MISCELLANEOUS OPS:
- *
- * wimax_reset() can be used to reset the device to power on state; by
- * default it issues a warm reset that maintains the same device
- * node. If that is not possible, it falls back to a cold reset
- * (device reconnect). The driver implements the backend to this
- * through wimax_dev->op_reset().

- *
- * @net_dev: [fill] Pointer to the &struct net_device this WiMAX

- *
- * @op_msg_from_user: [fill] Driver-specific operation to
- *     handle a raw message from user space to the driver. The

- *

- *     userspace (or any other agent) requesting the WiMAX device to
- *     change the RF Kill software switch (WIMAX_RF_ON or
- *     WIMAX_RF_OFF).
- *     If such hardware support is not present, it is assumed the
- *     radio cannot be switched off and it is always on (and the stack
- *     will error out when trying to switch it off). In such case,
- *     this function pointer can be left as NULL.
- *
- * @op_reset: [fill] Driver specific operation to reset the
- *     device.
- *     This operation should always attempt first a warm reset that
- *     does not disconnect the device from the bus and return 0.
- *     If that fails, it should resort to some sort of cold or bus
- *     reset (even if it implies a bus disconnection and device
- *     disappearance). In that case, -ENODEV should be returned to
- *     indicate the device is gone.
- *     This operation has to be synchronous, and return only when the
- *     reset is complete. In case of having had to resort to bus/cold
- *     reset implying a device disconnection, the call is allowed to
- *     return immediately.
- *     NOTE: wimax_dev->mutex is NOT locked when this op is being
- *     called; however, wimax_dev->mutex_reset IS locked to ensure
- *     serialization of calls to wimax_reset().
- *     See wimax_reset()'s documentation.
- *
- * @name: [fill] A way to identify this device. We need to register a
- *     name with many subsystems (rfkill, workqueue creation, etc).
- *     We can't use the network device name as that
- *     might change and in some instances we don't know it yet (until
- *     we don't call register_netdev()). So we generate an unique one
- *     using the driver name and device bus id, place it here and use
- *     it across the board. Recommended naming:
- *     DRIVERNAME-BUSNAME:BUSID (dev->bus->name, dev->bus_id).
- *
- * @id_table_node: [private] link to the list of wimax devices kept by
- *     id-table.c. Protected by it's own spinlock.
- *
- * @mutex: [private] Serializes all concurrent access and execution of
- *     operations.
- *
- * @mutex_reset: [private] Serializes reset operations. Needs to be a
- *     different mutex because as part of the reset operation, the
- *     driver has to call back into the stack to do things such as
- *     state change, that require wimax_dev->mutex.
- *
- * @state: [private] Current state of the WiMAX device.
- *
- * @rfkill: [private] integration into the RF-Kill infrastructure.
- *
- * @rf_sw: [private] State of the software radio switch (OFF/ON)
- *
- * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
- *
- * @debugfs_dentry: [private] Used to hook up a debugfs entry. This
- *     shows up in the debugfs root as wimax\:DEVICENAME.
- *
- * Description:
- * This structure defines a common interface to access all WiMAX
- * devices from different vendors and provides a common API as well as
- * a free-form device-specific messaging channel.
- *
- * Usage:
- *  1. Embed a &struct wimax_dev at *the beginning* the network
- *     device structure so that netdev_priv() points to it.
- *
- *  2. memset() it to zero
- *
- *  3. Initialize with wimax_dev_init(). This will leave the WiMAX
- *     device in the %__WIMAX_ST_NULL state.
- *
- *  4. Fill all the fields marked with [fill]; once called
- *     wimax_dev_add(), those fields CANNOT be modified.
- *
- *  5. Call wimax_dev_add() *after* registering the network
- *     device. This will leave the WiMAX device in the %WIMAX_ST_DOWN
- *     state.
- *     Protect the driver's net_device->open() against succeeding if
- *     the wimax device state is lower than %WIMAX_ST_DOWN.
- *
- *  6. Select when the device is going to be turned on/initialized;
- *     for example, it could be initialized on 'ifconfig up' (when the
- *     netdev op 'open()' is called on the driver).
- *
- * When the device is initialized (at `ifconfig up` time, or right
- * after calling wimax_dev_add() from _probe(), make sure the
- * following steps are taken
- *
- *  a. Move the device to %WIMAX_ST_UNINITIALIZED. This is needed so
- *     some API calls that shouldn't work until the device is ready
- *     can be blocked.
- *
- *  b. Initialize the device. Make sure to turn the SW radio switch
- *     off and move the device to state %WIMAX_ST_RADIO_OFF when
- *     done. When just initialized, a device should be left in RADIO
- *     OFF state until user space devices to turn it on.
- *
- *  c. Query the device for the state of the hardware rfkill switch
- *     and call wimax_rfkill_report_hw() and wimax_rfkill_report_sw()
- *     as needed. See below.
- *
- * wimax_dev_rm() undoes before unregistering the network device. Once
- * wimax_dev_add() is called, the driver can get called on the
- * wimax_dev->op_* function pointers
- *
- * CONCURRENCY:
- *
- * The stack provides a mutex for each device that will disallow API
- * calls happening concurrently; thus, op calls into the driver
- * through the wimax_dev->op*() function pointers will always be
- * serialized and *never* concurrent.
- *
- * For locking, take wimax_dev->mutex is taken; (most) operations in
- * the API have to check for wimax_dev_is_ready() to return 0 before
- * continuing (this is done internally).
- *
- * REFERENCE COUNTING:
- *
- * The WiMAX device is reference counted by the associated network
- * device. The only operation that can be used to reference the device
- * is wimax_dev_get_by_genl_info(), and the reference it acquires has
- * to be released with dev_put(wimax_dev->net_dev).
- *
- * RFKILL:
- *
- * At startup, both HW and SW radio switchess are assumed to be off.
- *
- * At initialization time [after calling wimax_dev_add()], have the
- * driver query the device for the status of the software and hardware
- * RF kill switches and call wimax_report_rfkill_hw() and
- * wimax_rfkill_report_sw() to indicate their state. If any is
- * missing, just call it to indicate it is ON (radio always on).
- *
- * Whenever the driver detects a change in the state of the RF kill
- * switches, it should call wimax_report_rfkill_hw() or
- * wimax_report_rfkill_sw() to report it to the stack.

- *
- * Messages are encoded as a binary netlink attribute using nla_put()
- * using type NLA_UNSPEC (as some versions of libnl still in

- * netlink/generic netlink attributes and headers).
- *
- * RECEPTION OF MESSAGES
- *
- * When a message is received from user space, it is passed verbatim
- * to the driver calling wimax_dev->op_msg_from_user(). The return
- * value from this function is passed back to user space as an ack
- * over the generic netlink protocol.
- *
- * The stack doesn't do any processing or interpretation of these
- * messages.
- *
- * SENDING MESSAGES
- *
- * Messages can be sent with wimax_msg().
- *
- * If the message delivery needs to happen on a different context to
- * that of its creation, wimax_msg_alloc() can be used to get a
