From 036cd1ec038f7e3a36740beaf2aa4a0d2e8ed2c1 Mon Sep 17 00:00:00 2001 From: Bruno Randolf Date: Sat, 19 Jan 2008 18:18:21 +0900 Subject: ath5k: use SWBA to detect IBSS HW merges use SWBA (software beacon alert) interrupts to keep track of the next beacon time und check if a HW merge (automatic TSF update) has happened on every received beacon with the same BSSID. this is necessary because the atheros hardware will silently update the local TSF in IBSS mode, but not its beacon timers. if the TSF is ahead of the beacon timers no beacons are sent until the timers wrap around (typically after about 1 minute). this solution is not very nice, since we have to look into every beacon, but there is apparently no other way to detect HW merges. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf Signed-off-by: John W.
