Subject: [PATCH] ath9k: fix beacon restart on channel change
Date: Thu, 30 Dec 2010 19:07:44 +0530 [thread overview]
Message-ID: <1293716264-4516-1-git-send-email-rmanoharan@atheros.com> (raw)
Restart the beacon timers only if the beacon
was already configured. Otherwise beacons timers
are restarted unnecessarily in unassociated state too.
