a185045c8d at76c50x-usb: Extract bssid from authentication frame
The driver at76c50x-usb is unable to authenticate with an AP since
kernel 2.6.31 for the following reason: The join command of the firmware
needs to be sent with the right bssid before any transmission can start.
Before kernel 2.6.31 mac80211 informed its drivers about the changing
bssid early enough for at76c50x-usb but during the development of 2.6.31
mac80211's behaviour changed. Now a new bssid is set after the
association.

This patch changes the tx routine of the driver at76c50x-usb in such a
way that a new bssid is extracted from an authentication frame and the
join command with that bssid is processed.

41b4b289ad at76c50x-usb: Move function at76_join() several lines up
This patch does a simple code move of at76_join() so that
at76_mac80211_tx() follows at76_join() in the driver's source file.

This is a preparatory patch for the following patch where we need
to call at76_join() from at76_mac80211_tx() in order to
authenticate successfully with a bssid.

c937019761 mac80211: avoid scheduling while atomic in mesh_rx_plink_frame
While mesh_rx_plink_frame holds sta->lock...

mesh_rx_plink_frame ->
	mesh_plink_inc_estab_count ->
		ieee80211_bss_info_change_notify

...but ieee80211_bss_info_change_notify is allowed to sleep.  A driver
taking advantage of that allowance can cause a scheduling while
atomic bug.  Similar paths exist for mesh_plink_dec_estab_count,
so work around those as well.

http://bugzilla.kernel.org/show_bug.cgi?id=16099

Also, correct a minor kerneldoc comment error (mismatched function names).

f90754c15f mac80211: Add interface for driver to temporarily disable dynamic ps
This mechanism introduced in this patch applies (at least) for hardware
designs using a single shared antenna for both WLAN and BT. In these designs,
the antenna must be toggled between WLAN and BT.

In those hardware, managing WLAN co-existence with Bluetooth requires WLAN
full power save whenever there is Bluetooth activity in order for WLAN to be
able to periodically relinquish the antenna to be used for BT. This is because
BT can only access the shared antenna when WLAN is idle or asleep.

Some hardware, for instance the wl1271, are able to indicate to the host
whenever there is BT traffic. In essence, the hardware will send an indication
to the host whenever there is, for example, SCO traffic or A2DP traffic, and
will send another indication when the traffic is over.

The hardware gets information of Bluetooth traffic via hardware co-existence
control lines - these lines are used to negotiate the shared antenna
ownership. The hardware will give the antenna to BT whenever WLAN is sleeping.

This patch adds the interface to mac80211 to facilitate temporarily disabling
of dynamic power save as per request of the WLAN driver. This interface will
immediately force WLAN to full powersave, hence allowing BT coexistence as
described above.

In these kind of shared antenna desings, when WLAN powersave is fully disabled,
Bluetooth will not work simultaneously with WLAN at all. This patch does not
address that problem. This interface will not change PSM state, so if PSM is
disabled it will remain so. Solving this problem requires knowledge about BT
state, and is best done in user-space.

Currently, detection in hwsim and ath9k can
detect that two sw scans are in flight at the

caused by a race condition, because the scan
complete callback is called too late, after
the lock has been dropped, so that a new scan
can be started before it is called.

It is also called too early semantically, as
it is currently called _after_ the return to
the operating channel -- it should be before
so that drivers know this is the operating
channel again.

62412a8f0d ath5k: remove pointless rx error overlay struct
ath5k_hw_rx_error was only used once, where we could easily just use
ath5k_hw_rx_status as well, so remove it.

a666819354 ath5k: use direct function calls for descriptors when possible
Use direct function calls for ath5k_hw_setup_rx_desc() and
ath5k_hw_setup_mrr_tx_desc() instead of a function pointer which always pointed
to the same function in the case of ath5k_hw_setup_rx_desc() and which is
easily unified in the case of ath5k_hw_setup_mrr_tx_desc().

Also simplify the initialization function for the remaining function pointers.

02a78b42f8 ath5k: move checks and stats into new function
Create a new function ath5k_receive_frame_ok() which checks for errors, updates
error statistics and tells us if we want to further "receive" this frame or
not. This way we can avoid a goto and have a cleaner separation between buffer
handling and other things.

8a89f063e7 ath5k: split descriptor handling and frame receive
Move frame reception into it's own function to have a clearer separation
between buffer and descriptor handling and things that are done when we
actually receive a frame.
