      mac80211: pass vif param to conf_tx() callback · 8a3a3c85
      Eliad Peller authored
      
      
      tx params should be configured per interface.
      add ieee80211_vif param to the conf_tx callback,
      and change all the drivers that use this callback.
      
      The following spatch was used:
      @rule1@
      struct ieee80211_ops ops;
      identifier conf_tx_op;
      @@
      	ops.conf_tx = conf_tx_op;
      
      @rule2@
      identifier rule1.conf_tx_op;
      identifier hw, queue, params;
      @@
      	conf_tx_op (
      -		struct ieee80211_hw *hw,
      +		struct ieee80211_hw *hw, struct ieee80211_vif *vif,
      		u16 queue,
      		const struct ieee80211_tx_queue_params *params) {...}

      mac80211: explicitly notify drivers of frame release · 40b96408
      Johannes Berg authored
      
      
      iwlwifi needs to know the number of frames that are
      going to be sent to a station while it is asleep so
      it can properly handle the uCode blocking of that
      station.
      
      Before uAPSD, we got by by telling the device that
      a single frame was going to be released whenever we
      encountered IEEE80211_TX_CTL_POLL_RESPONSE. With
      uAPSD, however, that is no longer possible since
      there could be more than a single frame.
      
      To support this model, add a new callback to notify
      drivers when frames are going to be released.

      mac80211: allow releasing driver-buffered frames · 4049e09a
      Johannes Berg authored
      
      
      If there are frames for a station buffered in
      the driver, mac80211 announces those in the TIM
      IE but there's no way to release them. Add new
      API to release such frames and use it when the
      station polls for a frame.
      
      Since the API will soon also be used for uAPSD
      it is easily extensible.
      
      Note that before this change drivers announcing
      driver-buffered frames in the TIM bit actually
      will respond to a PS-Poll with a potentially
      lower priority frame (if there are any frames
      buffered in mac80211), after this patch a driver
      that hasn't been changed will no longer respond
      at all. This only affects ath9k, which will need
      to be fixed to implement the new API.

      mac80211: Check for queued frames before entering power save. · e8306f98
      Vivek Natarajan authored
      
      
      In a highly noisy environment, the tx rate of the driver drops and
      the application slows down since it has not yet received ACKs for
      the frames already queued in the hardware. Since this ACK may take
      more than 100ms, stopping the dev queues for entering PS at this
      stage breaks applications, WMM test cases in my testing.
      If there are frames already pending in the tx queue, postponing the
      PS logic helps to avoid redundant queue stops. When power save is
      enabled by default and in a noisy environment, this API certainly
      helps in improving the average throughput.

      mac80211: support direct offchannel TX offload · 5f16a436
      Johannes Berg authored
      
      
      For devices supported by iwlwifi sometimes
      off-channel transmissions need to be handled
      by the device completely. To support this
      mac80211 needs to pass the frame directly
      to the driver and not through the TX path
      as the driver needs the frame and channel
      information at the same time.

      mac80211: make tx() operation return void · 7bb45683
      Johannes Berg authored
      
      
      The return value of the tx operation is commonly
      misused by drivers, leading to errors. All drivers
      will drop frames if they fail to TX the frame, and
      they must also properly manage the queues (if they
      didn't, mac80211 would already warn).
      
      Removing the ability for drivers to return a BUSY
      value also allows significant cleanups of the TX
      TX handling code in mac80211.
      
      Note that this also fixes a bug in ath9k_htc, the
      old "return -1" there was wrong.
