      mac80211: fix offloaded BA session traffic after hw restart · 4549cf2b
      Michal Kazior authored
      When starting an offloaded BA session it is
      unknown what starting sequence number should be
      used. Using last_seq worked in most cases except
      after hw restart.
      
      When hw restart is requested last_seq is
      (rightfully so) kept unmodified. This ended up
      with BA sessions being restarted with an aribtrary
      BA window values resulting in dropped frames until
      sequence numbers caught up.
      
      Instead of last_seq pick seqno of a first Rxed
      frame of a given BA session.
      
      This fixes stalled traffic after hw restart with
      offloaded BA sessions (currently only ath10k).

      mac80211: fix chantype recalc warning · a00f4f6e
      Michal Kazior authored
      When a device driver is unloaded local->interfaces
      list is cleared. If there was more than 1
      interface running and connected (bound to a
      chanctx) then chantype recalc was called and it
      ended up with compat being NULL causing a call
      trace warning.
      
      Warn if compat becomes NULL as a result of
      incompatible bss_conf.chandef of interfaces bound
      to a given channel context only.
      
      The call trace looked like this:

      mac80211: disable 40MHz support in case of 20MHz AP · 53b954ee
      Eliad Peller authored
      If the AP only advertises support for 20MHz (in the
      ht operation ie), disable 40MHz and VHT.
      
      This can improve interoperability with APs that
      don't like stations exceeding their own
      advertised capabilities.

      mac80211: don't duplicate station QoS capability data · a74a8c84
      Johannes Berg authored
      We currently track the QoS capability twice: for all peer stations
      in the WLAN_STA_WME flag, and for any clients associated to an AP
      interface separately for drivers in the sta->sta.wme field.
      
      Remove the WLAN_STA_WME flag and track the capability only in the
      driver-visible field, getting rid of the limitation that the field
      is only valid in AP mode.
