      mac80211: Extend the rate control API with an update callback · 81cb7623
      Sujith authored
      
      
      The AP can switch dynamically between 20/40 Mhz channel width,
      in which case we switch the local operating channel, but the
      rate control algorithm is not notified. This patch adds a new callback
      to indicate such changes to the RC algorithm.
      
      Currently, HT channel width change is notified, but this callback
      can be used to indicate any new requirements that might come up later on.

      mac80211: fix aggregation for hardware with ampdu queues · 96f5e66e
      Johannes Berg authored
      
      
      Hardware with AMPDU queues currently has broken aggregation.
      
      This patch fixes it by making all A-MPDUs go over the regular AC queues,
      but keeping track of the hardware queues in mac80211. As a first rough
      version, it actually stops the AC queue for extended periods of time,
      which can be removed by adding buffering internal to mac80211, but is
      currently not a huge problem because people rarely use multiple TIDs
      that are in the same AC (and iwlwifi currently doesn't operate as AP).
      
      This is a short-term fix, my current medium-term plan, which I hope to
      execute soon as well, but am not sure can finish before .30, looks like
      this:
       1) rework the internal queuing layer in mac80211 that we use for
          fragments if the driver stopped queue in the middle of a fragmented
          frame to be able to queue more frames at once (rather than just a
          single frame with its fragments)
       2) instead of stopping the entire AC queue, queue up the frames in a
          per-station/per-TID queue during aggregation session initiation,
          when the session has come up take all those frames and put them
          onto the queue from 1)
       3) push the ampdu queue layer abstraction this patch introduces in
          mac80211 into the driver, and remove the virtual queue stuff from
          mac80211 again
      
      This plan will probably also affect ath9k in that mac80211 queues the
      frames instead of passing them down, even when there are no ampdu queues.
