mac80211: A-MPDU Tx add MLME structures
This patch adds the needed structures to describe the Tx aggregation MLME per STA new: - struct tid_ampdu_tx: TID aggregation information (Tx) changed: - struct sta_ampdu_mlme: Tx aggregation information per TID and dialog token creator were added - struct sta_info: tid_to_tx_q added for tid<->tx queue mapping Signed-off-by: Ron Rindjunsky <ron.rindjunsky@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
