module_param(bool) used to counter-intuitively take an int. In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.
It's time to remove the int/unsigned int option. For this version
it'll simply give a warning, but it'll break next kernel version.
(Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false).

In ancient times it was necessary to manually initialize the bus field of an
spi_driver to spi_bus_type. These days this is done in spi_driver_register(),
so we can drop the manual assignment.
The patch was generated using the following coccinelle semantic patch:
// <smpl>
@@
identifier _driver;
@@
struct spi_driver _driver = {
.driver = {
- .bus = &spi_bus_type,
},
};

In the past, it was fine to simply call
dev_kfree_skb when it was impossible to
transmit a skb. However, with the new
tx status API:
"mac80211: implement wifi TX status"
Every loose skb needs to be handed back
to mac80211.

priv->work must not be synced while priv->mutex is locked, because
the mutex is taken in the work handler.
Move cancel_work_sync down to after the device shutdown code.
This is safe, because the work handler checks fw_state and bails out
early in case of a race.

Add uAPSD support to mac80211. This is probably not
possible with all devices, so advertising it with
the cfg80211 flag will be left up to drivers that
want it.
Due to my previous patches it is now a fairly
straight-forward extension. Drivers need to have
accurate TX status reporting for the EOSP frame.
For drivers that buffer themselves, the provided
APIs allow releasing the right number of frames,
but then drivers need to set EOSP and more-data
themselves. This is documented in more detail in
the new code itself.

"For best CPU usage and power consumption, having as few
frames as possible percolate through the stack is
desirable. Hence, the hardware should filter as much
as possible."
Note: Not all firmwares include the multicast filter
feature and the stack does not filter them either.
The ARP filter on the other hand was dropped from the
patch since it does not work correctly:
Quote from: Max Filippov <jcmvbkbc@gmail.com>
<http://www.spinics.net/lists/linux-wireless/msg67466.html>
"In the ARP case, when there's no other traffic on p54spi,
all ARP requests are dropped. But if there's some egress
traffic from p54spi, filter seems to work correctly:
only ARP requests that match filter pass through.
In the multicast case filter seems to work correctly, but
it treats broadcast as subject to that filtering too. By
default only 01:00:5e:00:00:01 gets into priv->mc_maclist,
so we miss all broadcasts.
These two filters seem to interfere:
- if we set ARP filter and multicast filter without bc
=> we miss all ARPs if there's no egress traffic;
- if we set ARP filter and multicast filter with bc or
don't set mc filter at all => we get all ARPs.
This effect does not depend on filter setup order."

This patch fixes a very serious off-by-one bug in
the driver, which could leave the device in an
unresponsive state.
The problem was that the extra_len variable [used to
reserve extra scratch buffer space for the firmware]
was left uninitialized. Because p54_assign_address
later needs the value to reserve additional space,
the resulting frame could be to big for the small
device's memory window and everything would
immediately come to a grinding halt.

The return value of the tx operation is commonly
misused by drivers, leading to errors. All drivers
will drop frames if they fail to TX the frame, and
they must also properly manage the queues (if they
didn't, mac80211 would already warn).
Removing the ability for drivers to return a BUSY
value also allows significant cleanups of the TX
TX handling code in mac80211.
Note that this also fixes a bug in ath9k_htc, the
old "return -1" there was wrong.

Commit: "p54: enhance rssi->dBm database import"
changed the way how the driver deals with the
rssical data. A new data format was necessary
and hence this patch.
NOTE: (for users with a custom eeprom binary)
I spent some time updating p54tools to support
the new format too: => (git available from)
http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git
It now comes with a simplistic script "n800_rssi2v2.sh"
which can be used to automate the conversion.

This patch fixes several shortcomings of the
previous implementation. Features of the
rewrite include:
* handles undocumented "0x0000" word at the
start of the frequency table.
(Affected some early? DELL 1450 USB devices
and my Symbol 5GHz miniPCI card.)
* supports more than just one reference point
per band. (Also needed for the Symbol card.)
* ships with default values in case the eeprom
data is damaged, absent or unsupported.

P54_HDR_FLAG_DATA_OUT_SEQNR is meant to tell the
firmware that "the frame's sequence number has
already been set by the application."
Whereas IEEE80211_TX_CTL_ASSIGN_SEQ is set for
frames which lack a valid sequence number and
either the driver or firmware has to assign one.
Yup, it's the exact opposite!
