I meant, that when stations in the PSM are handled correctly, then the log contains a records like this: kernel: wlan0: [18:86:ac:10:4b:88] power save mode on, 1 sta's in ps mode kernel: wlan0: [18:86:ac:10:4b:88] save frame with age 8, 1 now queued kernel: wlan0: ieee80211_beacon_update: TIM updated, pending 1, off 0, len 1 kernel: wlan0: [18:86:ac:10:4b:88] recv ps-poll, send packet, queue empty kernel: wlan0: ieee80211_beacon_update: TIM updated, pending 0, off 0, len 1 But the log's fragment from the kern/124753 doesn't contain records with the text "...TIM updated..." and "...recv ps-poll...". I had the very similar records in the log with the unpatched if_run.c. -- Alexander Zagrebin _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
