Subject: [PATCH v2 3/4] wl12xx: enable/disable beacon filtering on ap suspend/resume
Date: Mon, 6 Jun 2011 12:21:54 +0300 [thread overview]
Message-ID: <1307352115-28969-3-git-send-email-eliad@wizery.com> (raw)
In-Reply-To: <1307352115-28969-1-git-send-email-eliad@wizery.com>
Beacon filtering needs to be enabled so AP won't wake up by
by every received beacon.
