+ ath9k: Fix sequence number assignment for non-data frames
+
+ Since commit 558ff225de80ac95b132d3a115ddadcd64498b4f (ath9k: fix
+ ps-poll responses under a-mpdu sessions) non-data frames would have
+ gotten a sequence number from a TIDs sequence counter instead of
+ using the global sequence counter.
+
+ This can lead to instable connections.
+
+ To fix this only select the correct TID if we are processing a
+ data frame. Furthermore, prevent non-data frames to get a sequence
+ number from a TID sequence counter by adding a check to
+ ath_tx_setup_buffer.
