+ ath9k: do not set half/quarter channel flags in AR_PHY_MODE
+
+ 5/10 MHz channel bandwidth is configured via the PLL clock, instead of
+ the AR_PHY_MODE register. Using that register is AR93xx specific, and
+ makes the mode incompatible with earlier chipsets.
+
+ In some early versions, these flags were apparently applied at the wrong
+ point in time and thus did not cause connectivity issues, however now
+ they are causing problems, as pointed out in this OpenWrt ticket:

+ ath9k: fix ps-poll responses under a-mpdu sessions
+
+ When passing tx frames to the U-APSD queue for powersave poll responses,
+ the ath_atx_tid pointer needs to be passed to ath_tx_setup_buffer for
+ proper sequence number accounting.
+
+ This fixes high latency and connection stability issues with ath9k
+ running as AP and a few kinds of mobile phones as client, when PS-Poll
+ is heavily used
