>Description:

PS-Poll seems to be broken. My wife's MacBook Air generates a lot of
PS-Poll frames:
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 14 still queued
wlan1: [xx:xx:xx:d7:24:20] save frame with age 0, 15 now queued
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 14 still queued
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 13 still queued
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 12 still queued
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 11 still queued
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, send packet, 10 still queued

And later lots of these:
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, but queue empty
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, but queue empty
wlan1: [xx:xx:xx:d7:24:20] recv ps-poll, but queue empty

At this point the Atheros card isn't working and all stations
disassociate.
