+
+ It is currently possible to have a race due to the station PS
+ unblock work like this:
+ * station goes to sleep with frames buffered in the driver
+ * driver blocks wakeup
+ * station wakes up again
+ * driver flushes/returns frames, and unblocks, which schedules
+ the unblock work
+ * unblock work starts to run, and checks that the station is
+ awake (i.e. that the WLAN_STA_PS_STA flag isn't set)
+ * we process a received frame with PM=1, setting the flag again
+ * ieee80211_sta_ps_deliver_wakeup() runs, delivering all frames
+ to the driver, and then clearing the WLAN_STA_PS_DRIVER and
+ WLAN_STA_PS_STA flags
+
+ In this scenario, mac80211 will think that the station is awake,
+ while it really is asleep, and any TX'ed frames should be filtered
+ by the device (it will know that the station is sleeping) but then
+ passed to mac80211 again, which will not buffer it either as it
+ thinks the station is awake, and eventually the packets will be
+ dropped.
+
+ Fix this by moving the clearing of the flags to exactly where we
+ learn about the situation. This creates a problem of reordering,
+ so introduce another flag indicating that delivery is being done,
+ this new flag also queues frames and is cleared only while the
+ spinlock is held (which the queuing code also holds) so that any
+ concurrent delivery/TX is handled correctly.

+ mac80211: reduce packet loss notifications under load
+
+ During strong signal fluctuations under high throughput, few consecutive
+ failed A-MPDU transmissions can easily trigger packet loss notification,
+ and thus (in AP mode) client disconnection.
+
+ Reduce the number of false positives by checking the A-MPDU status flag
+ and treating a failed A-MPDU as a single packet.

+ 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.
