-    ath9k: avoid passing buffers to the hardware during flush
-    
-    The commit "ath9k: fix possible hang on flush" changed the receive code
-    to always link rx descriptors of processed frames, even when flushing.
-    In some cases, this leads to flushed rx buffers being passed to the
-    hardware while rx is already stopped.

-    The orinoco driver uses the cfg80211 API structs for internal

-    mac80211: Handle the CSA counters correctly
-    
-    Make the beacon CSA counters part of ieee80211_mutable_offsets and don't
-    decrement CSA counters when generating a beacon template. This permits the
-    driver to offload the CSA counters handling. Since mac80211 updates the probe
-    responses with the correct counter, the driver should sync the counter's value
-    with mac80211 using ieee80211_csa_update_counter function.

-    mac80211: disconnect iface if CSA unexpectedly fails
-    
-    It doesn't make much sense to leave a crippled

-    
-    As a side effect this will unblock tx queues with
-    CSA reason immediately after failure instead of
-    until after userspace requests interface to stop.
-    
-    This also gives userspace an opportunity to

-    rfkill-gpio: Use gpio cansleep version
-    
-    If gpio controller requires waiting for read and write
-    GPIO values, then we have to use the gpio cansleep api.
-    Fix the rfkill_gpio_set_power which calls only the
-    nonsleep version (causing kernel warning).
-    There is no problem to use the cansleep version here
-    because we are not in IRQ handler or similar context
-    (cf rfkill_set_block).

-    mac80211: ignore cqm during csa
-    
-    It is not guaranteed that multi-vif channel
-    switching is tightly synchronized. It makes sense
-    to ignore cqm (missing beacons, et al) while csa
-    is progressing and re-check it after it completes.

-    cfg80211: export interface stopping function
-    
-    This exports a new cfg80211_stop_iface() function.
-    
-    This is intended for driver internal interface
-    combination management and channel switching.
-    
-    Due to locking issues (it re-enters driver) the
-    call is asynchronous and uses cfg80211 event
-    list/worker.

-    mac80211: fix CSA tx queue stopping
-    
-    It was possible for tx queues to be stuck stopped
-    if AP CSA finalization failed. In that case
-    neither stop_ap nor do_stop woke the queues up.
-    This means it was impossible to perform tx at all
-    until driver was reloaded or a successful CSA was
-    performed later.
-    
-    It was possible to solve this in a simpler manner
-    however this is more robust and future proof
-    (having multi-vif CSA in mind).
-    
-    New sdata->csa_block_tx is introduced to keep
-    track of which interfaces requested tx to be
-    blocked for CSA. This is required because mac80211
-    stops all tx queues for that purpose. This means
-    queues must be awoken only when last tx-blocking
-    CSA interface is finished.
-    
-    It is still possible to have tx queues stopped
-    after CSA failure but as soon as offending
-    interfaces are stopped from userspace (stop_ap or
-    ifdown) tx queues are woken up properly.

-    These really can't trigger unless somebody messes up the code,
-    but don't make debugging it needlessly complicated, WARN and
-    return instead of BUG_ON().
+    The commit "ath9k: fix possible hang on flush" changed the receive code
+    to always link rx descriptors of processed frames, even when flushing.
+    In some cases, this leads to flushed rx buffers being passed to the
+    hardware while rx is already stopped.
