Larry Finger reported this issue. The driver, under certain
conditions, spews log messages like this:
wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 159/256
dur 1778/1504
These log messages turned out to be false alarms. Root cause was
that the AC was derived from the sk_buff::priority field. Fix was
to derive the AC from the sk_buff using skb_get_queue_mapping()
