There is a regression introduced with this patch.
On my ath9k AP + ath9k STA I get timeout for
management frames even when they are acked.

Attached syslog and iw event before and after
this patch.

I have seen it before in my testing and it gets
a lot worse with system load.  Sometimes it can
retry auth/assoc frames for 10 seconds before
connecting.
Anyway it always looses the first authentication frame.

I think I see what's happening -- can you try this patch?

I have tried and it doesn't do timeout anymore. I will continue
testing with more load.

Thanks,
