-Subject: [PATCH] ath9k: Correct TSF adjustment to align the beacon time
- correctly
-
-Beacons were not send out at (timestamp % beacon_time == 0) for interfaces
-other than the primary one. To send out beacons with the correct timestamp
-according to 10.1.3.2 of the 802.11 standard the tsf_adjustment has to be
-set to the negative time difference instead of positive. This way the
-later beacons get corrected to have a lower (and similar) timestamp with
-regard to the beacon from slot 0.
-
-I am not aware about any issues that have been caused by this.
