3. 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. ThereAqs 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 hasnAqt 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

4. 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 OKAqed starting it by calling ieee80211_start_tx_ba_cb_irqsafe, because the peer might receive the addBA frame and send a delBA right away!
