      ath10k: fix beacon deadlock · af21319f
      Michal Kazior 提交于
      This should fix a very rare occurrence of the following deadlock:

      To prevent this make sure to release ar->data_lock
      while calling to ath10k_wmi_beacon_send_ref_nowait().

      ath10k: prevent setting wrong key idx for station · 627613f8
      SenthilKumar Jegadeesan 提交于
      Ath10k driver sets wrong default key idx that results in
      sending unicast frames with multicast key.
      
      The reason for this behavior is that cached broadcast key
      is installed for station MAC address on association. After
      dot1x completes, unicast key is installed for station
      MAC address. Default key idx is set to broadcast key id when
      driver tries to send broadcast frame. This causes firmware
      to use broadcast key id to transmit unicast frames to stations.
      
      Used TX_USAGE flag to set default key for stations.
      
      Added callback for setting unicast default idx which will be
      invoked on every default key idx configuration.
