+ * 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
+ * (states in rows can go to states in columns where there is an X):
+ *
+ * UNINI RADIO READY SCAN CONNEC CONNEC

+ *
+ *
+ * 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:
+ *
+ * result = d_level_register_debugfs("PREFIX_", submodule_X, parent);
+ * if (result < 0)
+ * goto error;
+ *
+ * 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.

+ * Intel Corporation <linux-wimax@intel.com>

+ * - 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.

+
+ Usually these devices are controlled through an i2c bus, but other busses
+ may also be used.
+
+ The v4l2_subdev struct provides a way of accessing these devices in a
+ generic manner. Most operations that these sub-devices support fall in
+ a few categories: core ops, audio ops, video ops and tuner ops.
+
+ More categories can be added if needed, although this should remain a
+ limited set (no more than approx. 8 categories).
+
+ Each category has its own set of ops that subdev drivers can implement.
+
+ A subdev driver can leave the pointer to the category ops NULL if
+ it does not implement them (e.g. an audio subdev will generally not
+ implement the video category ops). The exception is the core category:
+ this must always be present.
+
+ These ops are all used internally so it is no problem to change, remove
+ or add ops or move ops from one to another category. Currently these
+ ops are based on the original ioctls, but since ops are not limited to
+ one argument there is room for improvement here once all i2c subdev

+ * 02110-1301, USA.
+ *
+ *
+ * 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 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 thorough 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 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().

+ *
+ * @op_msg_from_user: [fill] Driver-specific operation to

+ *
+ * @op_rfkill_sw_toggle: [fill] Driver-specific operation to act on

+ * change the RF Kill software switch (WIMAX_RF_ON or
+ * WIMAX_RF_OFF).
+ * If such hardware support is not present, it is assumed the

+ * 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
+ * dissapearance). 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 inmediately.
+ * 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 (input for 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.
+ *
+ * @rfkill_input: [private] virtual input device to process the
+ * hardware RF Kill switches.
+ *
+ * @rf_sw: [private] State of the software radio switch (OFF/ON)
+ *
+ * @rf_hw: [private] State of the hardware radio switch (OFF/ON)
+ *
+ * @debufs_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.
