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

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

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

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

453 We setup MAC_BSSID_DW1_BSS_BCN_NUM dynamically when numbers of active
454 beacons increase. Change default to 0 to tell hardware that we want to
455 send only one beacon as default.

463 rt2x00: change beaconing setup on RT2800
465 As reported by Matthias, on 5572 chip, even if we clear up TXWI
466 of corresponding beacon, hardware still try to send it or do other
467 action that increase power consumption peak up to 1A.
469 To avoid the issue, setup beaconing dynamically by configuring offsets
470 of currently active beacons and MAC_BSSID_DW1_BSS_BCN_NUM variable,
471 which limit number of beacons that hardware will try to send.

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

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

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