MEMBERS

27       mtx
28           mutex to protect all TX data (except non-NULL assignments to
29           tid_tx[idx], which are protected by the sta spinlock) tid_start_tx
30           is also protected by sta->lock.
31
32       tid_rx[IEEE80211_NUM_TIDS]
33           aggregation info for Rx per TID -- RCU protected
34
35       tid_rx_token[IEEE80211_NUM_TIDS]
36           dialog tokens for valid aggregation sessions
37
38       tid_rx_timer_expired[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]
39           bitmap indicating on which TIDs the RX timer expired until the work
40           for it runs
41
42       tid_rx_stop_requested[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]
43           bitmap indicating which BA sessions per TID the driver requested to
44           close until the work for it runs
45
46       tid_rx_manage_offl[BITS_TO_LONGS(2 *IEEE80211_NUM_TIDS)]
47           bitmap indicating which BA sessions were requested to be treated as
48           started/stopped due to offloading
49
50       agg_session_valid[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]
51           bitmap indicating which TID has a rx BA session open on
52
53       unexpected_agg[BITS_TO_LONGS(IEEE80211_NUM_TIDS)]
54           bitmap indicating which TID already sent a delBA due to unexpected
55           aggregation related frames outside a session
56
57       work
58           work struct for starting/stopping aggregation
59
60       tid_tx[IEEE80211_NUM_TIDS]
61           aggregation info for Tx per TID
62
63       tid_start_tx[IEEE80211_NUM_TIDS]
64           sessions where start was requested
65
66       last_addba_req_time[IEEE80211_NUM_TIDS]
67           timestamp of the last addBA request.
68
69       addba_req_num[IEEE80211_NUM_TIDS]
70           number of times addBA request has been sent.
71
72       dialog_token_allocator
73           dialog token enumerator for each new session;
