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!
