From bf0a26d31ba141b7f41976392ea393ce90ca64e3 Mon Sep 17 00:00:00 2001 From: Michal Kazior Date: Sat, 24 Jan 2015 12:14:51 +0200 Subject: [PATCH] ath10k: fix nullfunc workaround The workaround couldn't work correctly because the 802.11 header wasn't properly stripped of QoS Data bit so it wasn't recognized in the later parts of tx path as NullFunc frame and ended up in HTT Tx instead of HTT Mgmt Tx.
