In xmit path, devices that do full hardware crypto (including
TKIP MMIC) need no tailroom. For such devices, tailroom
reservation can be skipped if all the keys are programmed into
the hardware (i.e software crypto is not used for any of the
keys) and none of the keys wants software to generate Michael
MIC.

This patch adds a new API for setting a TX rate mask in
drivers that have rate control in either the firmware or hardware.
This can be used for various purposes, for example, masking out the
11b rates in P2P operation.

The patch "cfg80211: add a timer for invalid user reg hints"
introduced a regression for the case where a secondary identical
regulatory hint from a user is sent. What would happen is the
second hint would schedule delayed work in to catch a timeout
but since we are never processing it given that the hint was already
applied we'd always hit the timeout and and restore regulatory
settings back to world regulatory domain. This is fixed by simply
avoiding sheduling work if the hint was already applied.

The release timer has to expire "just" after a
frame is up for release. Currently, if the timer
callback starts on time, the "!time_after" check
above will start a new timer instead of
releasing the frames.

Currently mac80211 uses ieee80211_disable_40mhz_24ghz module
parameter to allow disabling 40MHz operation in the 2.4GHz band.
Move this handling from mac80211 to cfg80211 so that the feature
will be more generic.

Currently, the code to tear down BA sessions will
execute after queues are stopped, but attempt to
send frames, so those frames will just get queued,
which isn't intended. Move this code to before to
tear down the sessions properly.
Additionally, after stopping queues, flush the TX
queues in the driver driver to make sure all the
frames went out.

The locking with SMPS requests means that the
debugs file should lock the mgd mutex, not the
iflist mutex. Calls to __ieee80211_request_smps()
need to hold that mutex, so add an assertion.
This has always been wrong, but for some reason
never been noticed, probably because the locking
error only happens while unassociated.

This allows a driver to buffer frames for a PS station and tell mac80211
to wake it up even though mac80211 does not have any buffered frames for
it.
This is necessary for properly handling aggregation related buffering,
in ath9k, because the driver needs to keep its frames in order to keep
track of the Block-ACK window.

In the teardown path the reset command is sent to the controller,
this event causes the command timer to be reactivated.
So the timer is removed in two situations, when the adapter isn't
marked as UP and when we know that some command has been sent.

In a highly noisy environment, the tx rate of the driver drops and
the application slows down since it has not yet received ACKs for
the frames already queued in the hardware. Since this ACK may take
more than 100ms, stopping the dev queues for entering PS at this
stage breaks applications, WMM test cases in my testing.
If there are frames already pending in the tx queue, postponing the
PS logic helps to avoid redundant queue stops. When power save is
enabled by default and in a noisy environment, this API certainly
helps in improving the average throughput.
