Hello, Adrian. You wrote 15 =D0=BC=D0=B0=D1=8F 2013 =D0=B3., 22:34:26: AC> I've just committed my first pass of improved power save and ps-poll AC> support in AP mode to -HEAD.

Let me know if AC> things are better, worse or the same. r250675, my ususal test (300 mbit AP -> Client). Looks good. First of all, it gives me stable 100-150Mbit, so it could negotiate HT rates again without TCP :) And it sustain for 600 seconds in this mode, which was impossible before. There was several such messages: May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_suspend: tid=3D0xfffff= f8000d82230, bar_wait=3D0, bar_tx=3D0, called May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx_ready: c4:85:08:3f:= 9e:c2: tid=3D0xffffff8000d82230 (0), bar ready May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx: c4:85:08:3f:9e:c2:= tid=3D0xffffff8000d82230, called May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_tx: c4:85:08:3f:9e:c2:= tid=3D0xffffff8000d82230, new BAW left edge=3D676 May 16 12:57:31 gateway kernel: ath0: ath_bar_response: c4:85:08:3f:9e:c2: = called; tap=3D0xffffff8000d7f3a0, atid=3D0xffffff8000d82230, txa_tid=3D0, a= tid->tid=3D0, status=3D0, attempts=3D1 May 16 12:57:31 gateway kernel: ath0: ath_tx_tid_bar_unsuspend: c4:85:08:3f= :9e:c2: tid=3D0xffffff8000d82230, called But no full stalls.

At second test, after ~300 seconds of test in battery mode it drops to no= n-N speeds and never recovered. --=20 // Black Lion AKA Lev Serebryakov <lev@FreeBSD.org>
