+    ath9k_hw: fix PLL clock initialization for newer SoC
+    
+    On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
+    register changed. This currently breaks at least 5/10 MHz operation.
+    AR933x uses the old layout.
+    
+    It might also have been causing other stability issues because of the
+    different location of the PLL_BYPASS bit which needs to be set during
+    PLL clock initialization.
+    
+    This patch also removes more instances of hardcoded register values in
+    favor of properly computed ones with the PLL_BYPASS bit added.

+    ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
+    
+    The cycpwr_thr1 value needs to be lower on the extension channel than on
+    the control channel, similar to how the register settings are programmed
+    in the initvals.
+    
+    Also drop the unnecessary check for HT40 - this register can always be
+    written. This patch has been reported to improve HT40 stability and
+    throughput in some environments.

+    ath9k: fix pending tx frames accounting
+    
+    Packets originally buffered for the regular hardware tx queues can end
+    up being transmitted through the U-APSD queue (via PS-Poll or U-APSD).
+    When packets are dropped due to retransmit failures, the pending frames
+    counter is not always updated properly.
+    Fix this by keeping track of the queue that a frame was accounted for in
+    the ath_frame_info struct, and using that on completion to decide
+    whether the counter should be updated.

+    
+    Using csa counter offsets which are embedded in

+    RCU assignment) is much safer.

+    cfg80211: make ethtool the driver's responsibility
+    
+    Currently, cfg80211 tries to implement ethtool, but that doesn't
+    really scale well, with all the different operations. Make the
+    lower-level driver responsible for it, which currently only has
+    an effect on mac80211. It will similarly not scale well at that
+    level though, since mac80211 also has many drivers.
+    
+    To cleanly implement this in mac80211, introduce a new file and
+    move some code to appropriate places.

+    mac80211: fix station/driver powersave race
+    
+    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.
