MEMBERS

mtx

mutex to protect all TX data (except non-NULL assignments to tid_tx[idx], which are protected by the sta spinlock) tid_start_tx is also protected by sta->lock.

tid_rx[IEEE80211_NUM_TIDS]

aggregation info for Rx per TID -- RCU protected

tid_rx_timer_expired[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]

bitmap indicating on which TIDs the RX timer expired until the work for it runs

tid_rx_stop_requested[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]

bitmap indicating which BA sessions per TID the driver requested to close until the work for it runs

work

work struct for starting/stopping aggregation

tid_tx[IEEE80211_NUM_TIDS]

aggregation info for Tx per TID

tid_start_tx[IEEE80211_NUM_TIDS]

sessions where start was requested

last_addba_req_time[IEEE80211_NUM_TIDS]

timestamp of the last addBA request.

addba_req_num[IEEE80211_NUM_TIDS]

number of times addBA request has been sent.

dialog_token_allocator

dialog token enumerator for each new session;
