[14/28] mac80211: timeout a single frame in the rx reorder buffer

From: Greg KH <gregkh@linuxfoundation.org>
Date: 2012-02-17 00:59:57
Also in: lkml

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eliad Peller <redacted>

commit 07ae2dfcf4f7143ce191c6436da1c33f179af0d6 upstream.

The current code checks for stored_mpdu_num > 1, causing
the reorder_timer to be triggered indefinitely, but the
frame is never timed-out (until the next packet is received)
