I've seen other funny stuff where an AP will crash hard(-ish?) and the associated stations
take a long time to figure out their AP is dead.  Could be related to this
maybe..or maybe was something else.  I have not investigated closely.

I'd be happy to have all the beacon miss stuff move to the driver..seems
a waste of limited resources in the firmware.

Thanks,
Ben
