3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Larry Finger <Larry.Finger@lwfinger.net>
commit 5f9186990ec4579ee5b7a99b3254c29eda479f36 upstream.
Beginning with kernel 3.13, this driver fails on some systems. The problem was bisected to:
Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau <nbd@openwrt.org> Title: mac80211: send control port protocol frames to the VO queue
There is noting wrong with the above commit. The regression occurs because V0 queue on RTL8192SE cards uses priority 6, not the usual 7. The fix is to modify the rtl8192se routine that sets the correct transmit queue.
