| Subject: rtlwifi: rtl8192se: Fix regression due to commit 1bf4bbb |
| |
| 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. |
