The problem was bisected to: Commit 1bf4bbb4024dcdab5e57634dd8ae1072d42a53ac Author: Felix Fietkau 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.
