Hi,

I bisected a regression in ath9k and ended up at this commit:
179c5b22373511b9e8f73183f03d89e92278ab3e
(558ff225de80ac95b132d3a115ddadcd64498b4f upstream): "ath9k: fix ps-poll
responses under a-mpdu sessions"

My Sparklan WPEA-127N card (168c:0030), which works in 802.11n AP mode with
hostapd, works with extreme latencies after this commit and becomes
absolutely unusable.

Oddly enough, this commit is supposed to fix high latencies, but I haven't
seen problems before this.

I'd be happy to help in further investigation.

Thanks, Jozsef
