This patch squashes a few old bugs, which have been around since
the initial version of p54usb in one form or another.
we never freed a orphaned frame, when were denied the resources,
which are necessary to pass the data into the usb subsystem.
As a result we could end up with a full queue that wasn't emptied,
until the device was brought down.

"Ath5k: unify resets"
introduced a regression into 2.6.28 where the PCU registers are never
initialized, due to ath5k_reset() always passing true for change_channel.
We subsequently program a lot of these registers but several may start
in an unknown state.

Using the enable_beacon flag allows some simplifications and fixes
some corner cases in beacon handling. This change adds a state
variable for beaconing in ath5k_beacon_config and handles both
enabling and disabling, thus eliminating the need for
ath5k_beacon_disable. We also now configure the beacon when any
of the beacon parameters change, so ath5k_beacon_reconfig is no
longer needed (its mmiowb gets moved to ath5k_beacon_config).
Finally, by locking around the whole config function, we don't
need to worry about clearing the interrupt mask register before
installing the new mask.
The upshot is this correctly disables beaconing when the interfaces
are taken down, it fixes a potential restarting of beaconing
when ath5k_reset() is called, and ensures that updates to the
beacon interval take effect immediately.

We were not differentiating quality between legacy and HT
configurations. We change this to consider the differences.
New theory for reporting quality:
At a hardware RSSI of 45 you will be able to use MCS 7 reliably.
At a hardware RSSI of 45 you will be able to use MCS 15 reliably.
At a hardware RSSI of 35 you should be able use 54 Mbps reliably.
MCS 7 is the highets MCS index usable by a 1-stream device.
MCS 15 is the highest MCS index usable by a 2-stream device.
All ath9k devices are either 1-stream or 2-stream.
How many bars you see is derived from the qual reporting.
A more elaborate scheme can be used here but it requires tables
of SNR/throughput for each possible mode used. For the MCS table
you can refer to the wireless wiki:

The SDIO driver sets the surpriseremoved flag before calling
lbs_remove_card. With IEEE PS enabled, lbs_remove_card must issue a
command to exit IEEE PS mode, however with that flag set the command
path is blocked and the card is never taken out of IEEE PS mode. This
step is required to ensure that the driver can be reloaded. This patch
moves the setting of surpriseremoved after lbs_remove_card is called.
Tested with V9 firmware by ensuring that IEEE PS is disabled when the
driver is removed. Reloading the driver is not fully tested due to a
separate issue with module reload in the SDIO driver, however this
patch at least leaves the card in a better state when we bring the
driver down.

The SPI driver does a couple of card cleanup steps in the wrong order on
module removal. If IEEE PS is enabled, this results in the card being
left in IEEE PS mode and subsequent failures to reload the module. The
problem is that the surpriseremoved flag is set before calling
lbs_remove_card, but that function needs to issue a command to exit IEEE
PS mode (the flag blocks the command path). In addition, lbs_stop_card
should be called first because it clears out any pending commands.
Tested on a GSPI device with V9 firmware by confirming that we can
reload the module with or without IEEE PS enabled.
Also fix a warning from the wrong uint format in a printk.

This introduces a new NL80211_CMD_TESTMODE for testing
and calibration use with nl80211. There's no multiplexing
like like iwpriv had, and the command is not available by
default, it needs to be explicitly enabled in Kconfig and
shouldn't be enabled in most kernels.
The command requires a wiphy index or interface index to
identify the device to operate on, and the new TESTDATA
attribute. There also is API for sending replies to the
command, and testmode multicast messages (on a testmode
multicast group).
I've also updated mac80211 to be able to pass through the
command to the driver, since it itself doesn't implement
the testmode command.
Additionally, to give people an idea of how to use the
command, I've added a little code to hwsim that makes use
of the new command to set the powersave mode, this is
currently done via debugfs and should remain there, and
the testmode command only serves as an example of how to
use this best -- with nested netlink attributes in the
TESTDATA attribute. A hwsim testmode tool can be found at
http://git.sipsolutions.net/hwsim.git/. This tool is BSD
licensed so people can easily use it as a basis for their
own internal fabrication and validation tools.

max_nrg_cck value inside the sensitivity range structure is not needed
for sensitivity calibration.
Keep the parameter in sensitivity structure but set the value to "0" in case
needed in the future implementation.

In 5150 there is a long delay between the AGC(Automatic Gain Control) command
till the RF is stabilized causing us to miss detections when there was
adjacent channel noise, so we need to adjusted the Sensitivity calibration
for 5150 differently.

With shorter CAM timeouts, the logs get flooded with "psm enabled" and "psm
disabled traces. This patch changes it from wl1251_info to wl1251_debug, so
they are only shown if DEBUF_PSM is enabled.

CMD_TEST via netlink API has been broken since
e29c3f59cfbc38c3b481a2694b08962da19c4664: cmd and acx interface rework.
The user of the interface sends the request in a buffer without the
wl12xx_command header but expects the response to have the wl12xx_command
header (with id and status).
This patch reverts the e29c3f5 commit for cmd.c:wl12xx_cmd_test
and implements the needed wrapper functionality in netlink.c. Now the
API of wl12xx_cmd_test and rest of wl12xx_cmd_* commands in cmd.c are
similar.
