      ath6kl: Remove useless initialization in ath6kl_read_fwlogs() · e80ec84d
      Raja Mani authored
      ath6kl_read_fwlogs() assigns the value zero to the variable 'ret'
      at the time of declaration. Later, return value of ath6kl_diag_read32()
      repalces the init value. Hence removing useless zero assignment.

      ath6kl: Add support for uAPSD · c1762a3f
      Thirumalai Pachamuthu authored
      * A new APSD power save queue is added in the station structure.
      * When a station has APSD capability and goes to power save, the frame
        designated to the station will be buffered in APSD queue.
      * When the host receives a frame which the firmware marked as trigger,
        host delivers the buffered frame from the APSD power save queue.
        Number of frames to deliver is decided by MAX SP length.
      * When a station moves from sleep to awake state, all frames buffered
        in APSD power save queue are sent to the firmware.
      * When a station is disconnected, all frames bufferes in APSD power save
        queue are dropped.
      * When the host queues the first frame to the APSD queue or removes the
        last frame from the APSD queue, it is indicated to the firmware using
        WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.
      
      kvalo: fix buggy handling of sks queues, made it more obvious
      the user priority when wmm is disabled, remove unneed else block and
      combined some variable declarations

      ath6kl: Fix listen interval handling · 8232736d
      Sujith Manoharan authored
      This patch addresses a few problems with the commit:
      
      "ath6kl: Implement support for listen interval from userspace"
      
      * The debugfs file required for reading/writing the listen interval
        wasn't created. Fix this.
      
      * The interface index was being hardcoded to zero. Fix this.
      
      * Two separate parameters, "listen_interval_time and listen_interval_beacons"
        were being used. This fails to work as expected because the FW assigns
        higher precedence to "listen_interval_beacons" and "listen_interval_time"
        ends up being never used at all.
      
        To handle this, fix the host driver to exclusively use listen interval
        based on units of beacon intervals.
      
      To set the listen interval, a user would now do something like this:
      
      echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval
      
      kvalo: fix two checkpatch warnings

      ath6kl: Remove redundant pointer check · 4a8ce2fd
      Sujith Manoharan authored
      'params' is already used earlier and there is no point
      in checking for a NULL condition again.
