IEEE80211_STA_PS_TRA(9) 				     Advanced driver interface					   IEEE80211_STA_PS_TRA(9)

NAME

       ieee80211_sta_ps_transition_ni - PS transition for connected sta (in process context)

SYNOPSIS

       int ieee80211_sta_ps_transition_ni(struct ieee80211_sta * sta, bool start);

ARGUMENTS

       sta
	   currently connected sta

       start
	   start or stop PS

DESCRIPTION

       Like ieee80211_sta_ps_transition but can be called in process context (internally disables bottom halves). Concurrent call restriction
       still applies.

RETURN

       Like ieee80211_sta_ps_transition.

       };

MEMBERS

       mtx
	   mutex to protect all TX data (except non-NULL assignments to tid_tx[idx], which are protected by the sta spinlock)

       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;
