-Subject: [PATCH] ath9k: fix transmitting to stations in dynamic SMPS mode
-
-When transmitting to a receiver in dynamic SMPS mode, all transmissions that
-use multiple spatial streams need to be sent using CTS-to-self or RTS/CTS to
-give the receiver's extra chains some time to wake up.
-This fixes the tx rate getting stuck at <= MCS7 for some clients, especially
-Intel ones, which make aggressive use of SMPS.

-Subject: [PATCH] mac80211: fix TXQ AC confusion
-
-Normally, TXQs have
-
- txq->tid = tid;
- txq->ac = ieee80211_ac_from_tid(tid);
-
-However, the special management TXQ actually has
-
- txq->tid = IEEE80211_NUM_TIDS; // 16
- txq->ac = IEEE80211_AC_VO;
-
-This makes sense, but ieee80211_ac_from_tid(16) is the same
-as ieee80211_ac_from_tid(0) which is just IEEE80211_AC_BE.
-
-Now, normally this is fine. However, if the netdev queues
-were stopped, then the code in ieee80211_tx_dequeue() will
-propagate the stop from the interface (vif->txqs_stopped[])
-if the AC 2 (ieee80211_ac_from_tid(txq->tid)) is marked as
-stopped. On wake, however, __ieee80211_wake_txqs() will wake
-the TXQ if AC 0 (txq->ac) is woken up.
-
-If a driver stops all queues with ieee80211_stop_tx_queues()
-and then wakes them again with ieee80211_wake_tx_queues(),
-the ieee80211_wake_txqs() tasklet will run to resync queue
-and TXQ state. If all queues were woken, then what'll happen
-is that _ieee80211_wake_txqs() will run in order of HW queues
-0-3, typically (and certainly for iwlwifi) corresponding to
-ACs 0-3, so it'll call __ieee80211_wake_txqs() for each AC in
-order 0-3.
-
-When __ieee80211_wake_txqs() is called for AC 0 (VO) that'll
-wake up the management TXQ (remember its tid is 16), and the
-driver's wake_tx_queue() will be called. That tries to get a
-frame, which will immediately *stop* the TXQ again, because
-now we check against AC 2, and AC 2 hasn't yet been marked as
-woken up again in sdata->vif.txqs_stopped[] since we're only
-in the __ieee80211_wake_txqs() call for AC 0.
-
-Thus, the management TXQ will never be started again.
-
-Fix this by checking txq->ac directly instead of calculating
-the AC as ieee80211_ac_from_tid(txq->tid).
-
-Fixes: adf8ed01e4fd ("mac80211: add an optional TXQ for other PS-buffered frames")
