aggregation info for Rx per TID -- RCU protected
bitmap indicating on which TIDs the RX timer expired until the work for it runs
work struct for starting/stopping aggregation
aggregation info for Tx per TID
sessions where start was requested
number of times addBA request has been sent.
dialog token enumerator for each new session;
