    NativeWifi tx mode expects QoS Data frames to be
    delivered as Data frames with QoS part (e.g. tid)
    being delievered out-of-band in fw tx command.
    
    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.
