Subject: [PATCH] mac80211: don't return beacons when mesh is disabled
Date: Tue, 18 Jan 2011 13:45:32 +0100	[thread overview]
Message-ID: <1295354732.3563.18.camel@jlt3.sipsolutions.net> (raw)

From: Johannes Berg <johannes.berg@intel.com>

When mesh is disabled, mac80211 was returning
beacons with an empty mesh ID. That isn't
desirable, even if drivers shouldn't be trying
to get beacons to start with.
