I am getting some disconnections becasue of failed
nullfunc in my ath9k ap+sta test setup. The auth/assoc
don't timeout but nullfunc does.

I have checked in wireshark and all nullfunc were
properly acknowledged.
Attached syslog + iw event.

Do you have any idea where it comes from or should
I start looking at it?
