      ath10k: setup maximum number of supported stations · 37a0b394
      Janusz.Dziedzic@tieto.com 提交于
      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 提交于
      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 提交于
      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.
