      ath10k: setup maximum number of supported stations · 37a0b394
      Janusz.Dziedzic@tieto.com authored
      
      
      Setup maximum number of associated stations supported in
      AP/P2P_GO mode.
      
      This allow hostapd/wpa_supplicant to play with that limit
      and set more information (eg. P2P group limit bit for P2P_GO).

      ath10k: strip qos data bit always · 8bad8dcd
      Michal Kazior authored
      
      
      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.

      cfg80211: add bss_type and privacy arguments in cfg80211_get_bss() · 6eb18137
      Dedy Lansky authored
      
      
      802.11ad adds new a network type (PBSS) and changes the capability
      field interpretation for the DMG (60G) band.
      The same 2 bits that were interpreted as "ESS" and "IBSS" before are
      re-used as a 2-bit field with 3 valid values (and 1 reserved). Valid
      values are: "IBSS", "PBSS" (new) and "AP".
      
      In order to get the BSS struct for the new PBSS networks, change the
      cfg80211_get_bss() function to take a new enum ieee80211_bss_type
      argument with the valid network types, as "capa_mask" and "capa_val"
      no longer work correctly (the search must be band-aware now.)
      
      The remaining bits in "capa_mask" and "capa_val" are used only for
      privacy matching so replace those two with a privacy enum as well.

      ath10k: prevent setting wrong key idx for station · 627613f8
      SenthilKumar Jegadeesan authored
      
      
      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.
