3.6.11.6 stable review patch.
If anyone has any objections, please let me know.
------------------
From: Johannes Berg <johannes.b...@intel.com>
[ Upstream commit 2b9ccd4e4308272e5aec614b77c5385e7ec2ec90 ]
In AP mode, ignore frames with mis-matched BSSID that aren't
multicast or sent to the correct destination. This fixes
reporting public action frames to userspace multiple times
on multiple virtual AP interfaces.
