ath9k: fix sequence number assigment for non-AMPDU QoS data frames
wireless-testing commit 04caf863750bc7e042d1e8d57e5ce9d6326ab435 ('ath9k: more tx setup cleanups') merged tx path code for HT vs non-HT frames, however it did not pass the tid pointer to ath_tx_send_normal, causing an inconsistency between AMPDU vs non-AMPDU sequence number handling. Fix this by always passing in the tid pointer for all QoS data frames. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
