Subject: [PATCH 16/19] rt2x00: Don't treat ATIM queue as second beacon queue.
Date: Thu, 3 Mar 2011 19:46:09 +0100 [thread overview]
Message-ID: <201103031946.09972.IvDoorn@gmail.com> (raw)
In-Reply-To: <201103031945.40473.IvDoorn@gmail.com>
From: Gertjan van Wingerde <gwingerde@gmail.com>
Current code for the atim queue is strange, as it is considered in the
rt2x00_dev structure as a second beacon queue.
Normalize this by letting the atim queue have its own struct data_queue
pointer in the rt2x00_dev structure.
