IEEE80211_STOP_TX_BA(9) Rate control interface IEEE80211_STOP_TX_BA(9)NAME
ieee80211_stop_tx_ba_cb_irqsafe - low level driver ready to stop aggregate.
SYNOPSIS
void ieee80211_stop_tx_ba_cb_irqsafe(struct ieee80211_vif * vif, const u8 * ra, u16 tid);
ARGUMENTS
vif
struct ieee80211_vif pointer from the add_interface callback
ra
receiver address of the BA session recipient.
tid
the desired TID to BA on.
DESCRIPTION
This function must be called by low level driver once it has finished with preparations for the BA session tear down. It can be called from
any context.

ENUM IEEE80211_AMPDU(9) Advanced driver interface ENUM IEEE80211_AMPDU(9)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!
