First part of my problem is that I had some extra debugging turned on and
that was being sent to serial console, which is slow.

But, even with that off I am still seeing ~200ms at best.

Ath9k system on crappy old Atom processors usually completes in
less than 20ms for comparison.

Off to go spelunking in the ath10k code :P

Thanks,
