With both BCM4313 and BCM943224 cards, brcm80211 spams my logs with messages:

wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 159/256 dur 1778/1504
wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 137/256 dur 1602/1504
wl0: wlc_d11hdrs_mac80211: AC_BE txop exceeded phylen 382/256 dur 3562/1504

Thanks,

Larry

This actually means that mac80211 is giving us transmit packets which
violate the txop duration. I am not sure whether this is actually true or
we did not honour the conf_tx callback. I think we should put this one on
our todo list.

Likely it is a problem in our driver. I have been victimized to take a
look at it, so consider me your point of this contact for this one ;-)
I'll keep you guys posted.

Bye, Roland.

Are you saying you expect mac80211 to fragment packets that don't fit
into a txop? That's not done for sure.
