+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.

+Subject: [PATCH] ath9k: Handle channel context in get_/set_/reset_tsf
+
+The ath9k TSF handling routines need to be aware of the channel context that
+is being modified. With this change the TSF related values that are stored
+in each channel context will be correctly tracked and the harware will only
+be updated if the modified context is currently the active one.
+
+Without this change the TSF modifications done using these routines would
+for example be lost during a hardware reset as done by ath_complete_reset.

+Subject: [PATCH] ath9k: Use tsf offset helper in ath9k_hw_reset
+
+These changes make ath9k_hw_reset more consistent with other places that
+handle the TSF value by using the same helper routine.
+
+A slight improvement is to not assume that a fixed time of 1.5ms has
+passed for the initval writes when compared to the first write attempt.
+Instead the TSF value is re-calculated which will yield a higher accuracy
+of the restored TSF timer.

+Subject: [PATCH] ath9k: Fix beacon configuration for addition/removal of
+ interfaces
+
+This patch fixes some issues with interface reconfiguration. It could
+for example happen that an AP interface in beacon slot 0 was removed
+leaving an IBSS station in one of the other slots. When this happens
+the driver never sends out the beacon as it only tries to send a beacon
+from slot 0.
+
+Appart from that the tracking of required changes to the beacon config is
+relatively complicated and prone to errors.
+
+The approach taken here is to solve reconfiguration issues is to
+reconfigure the beacons when any interface changes. This means that
+the complexity of deciding whether an interface change may modify the
+beacon configuration is gone. It also means that the beacon config will
+be reliably updated when an interface is removed.
+
+The issue that a single non-AP interface might not be in beacon
+slot 0 and wouldn't be send out is solved by moving it into the
+first slot. The TSF value in hardware is adjusted accordingly so
+that the timestamp of the beacons stay consistent.
