NAME

       enum_ieee80211_ampdu_mlme_action - A-MPDU actions

SYNOPSIS

       enum ieee80211_ampdu_mlme_action {
	 IEEE80211_AMPDU_RX_START,
	 IEEE80211_AMPDU_RX_STOP,
	 IEEE80211_AMPDU_TX_START,
	 IEEE80211_AMPDU_TX_STOP_CONT,
	 IEEE80211_AMPDU_TX_STOP_FLUSH,
	 IEEE80211_AMPDU_TX_STOP_FLUSH_CONT,
	 IEEE80211_AMPDU_TX_OPERATIONAL
       };

CONSTANTS

       IEEE80211_AMPDU_RX_START
	   start RX aggregation

       IEEE80211_AMPDU_RX_STOP
	   stop RX aggregation

       IEEE80211_AMPDU_TX_START
	   start TX aggregation

       IEEE80211_AMPDU_TX_STOP_CONT
	   stop TX aggregation but continue transmitting queued packets, now unaggregated. After all packets are transmitted the driver has to
	   call ieee80211_stop_tx_ba_cb_irqsafe.

       IEEE80211_AMPDU_TX_STOP_FLUSH
	   stop TX aggregation and flush all packets, called when the station is removed. There's no need or reason to call
	   ieee80211_stop_tx_ba_cb_irqsafe in this case as mac80211 assumes the session is gone and removes the station.

       IEEE80211_AMPDU_TX_STOP_FLUSH_CONT
	   called when TX aggregation is stopped but the driver hasn't called ieee80211_stop_tx_ba_cb_irqsafe yet and now the connection is
	   dropped and the station will be removed. Drivers should clean up and drop remaining packets when this is called.

       IEEE80211_AMPDU_TX_OPERATIONAL
	   TX aggregation has become operational

DESCRIPTION

       These flags are used with the ampdu_action callback in struct ieee80211_ops to indicate which action is needed.

       Note that drivers MUST be able to deal with a TX aggregation session being stopped even before they OK'ed starting it by calling
       ieee80211_start_tx_ba_cb_irqsafe, because the peer might receive the addBA frame and send a delBA right away!
