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.
