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

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

From: Felix Fietkau <nbd@openwrt.org>

commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac upstream.

Improves reliability of wifi connections with WPA, since authentication
frames are prioritized over normal traffic and also typically exempt
from aggregation.
