The QoS bit wasn't stripped before submitting to firmware. Stripping fixes two known problems: * qca6174 IOT with some APs, e.g. Cisco AIR-AP 1252 (which would crash after ath10k association). Some ath9k APs would crash as well. * sniffing own tx frames via radiotap because, e.g. wireshark was seeing QoS bit set but since QoS Control was stripped in ath10k it would parse beginning of LLC/SNAP >From debugability point of view this removes the ability to distinguish QoS from non-QoS frames when sniffing own tx via radiotap. On the other hand frames can be now parsed correctly without special software modification. Signed-off-by: Michal Kazior Signed-off-by: Kalle Valo --- Reading git-diff-tree failed
