Subject: [PATCH 08/10] rt2x00: Correctly kill beacon queue
Date: Mon, 30 Aug 2010 21:14:56 +0200	[thread overview]
Message-ID: <201008302114.56989.IvDoorn@gmail.com> (raw)
In-Reply-To: <201008302114.38933.IvDoorn@gmail.com>

USB devices upload their beacon and then automatically send
it out every beacon interval. However when killing a TX queue
we only kill the URB and not the actual transmission of the beacon.

This will reset the Beacon register to prevent any beacons from
being transmitted.
