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;
