- rt2x00: change order when stop beaconing
-
- When no beaconing is needed, first stop beacon queue (disable beaconing
- globally) to avoid possible sending of not prepared beacon on short
- period after clearing beacon and before stop of BCN queue.

- rt2x00: change beaconing setup on RT2800
-
- As reported by Matthias, on 5572 chip, even if we clear up TXWI
- of corresponding beacon, hardware still try to send it or do other
- action that increase power consumption peak up to 1A.
+ ath9k_hw: disable hardware ad-hoc flag on ar934x rev 3
- To avoid the issue, setup beaconing dynamically by configuring offsets
- of currently active beacons and MAC_BSSID_DW1_BSS_BCN_NUM variable,
- which limit number of beacons that hardware will try to send.
+ On AR934x rev 3, settin the ad-hoc flag completely messes up hardware
+ state - beacons get stuck, almost no packets make it out, hardware is
+ constantly reset.

- 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
+ ath9k: use ah->get_mac_revision for all SoC devices if available
- 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.
+ It is needed for AR934x as well
- 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
+ ath5k: add missing include for debug code
- 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.
+ Needed for calling vmalloc()/vfree()

- 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.
+ Revert "ath5k: Remove AHB bus support"
- Signed-off-by: Felix Fietkau <nbd@openwrt.org>
+ This reverts commit 093ec3c5337434f40d77c1af06c139da3e5ba6dc.
