- Subject: [PATCH] ath9k: Process beacons properly
- When the current operating channel context has
- been marked as ATH_CHANCTX_STATE_FORCE_ACTIVE,
- do not process beacons that might be received,
- since we have to wait for the station to become
- authorized.
- Also, since the cached TSF value will be zero
- initially do not rearm the timer in this
- case when a beacon is received, since it results
- in spurious values.
