Adrian Chadd ef347e56a2 [ath] add a placeholder event for debuggin EDMA TX FIFO push events.
Some later code I'll commit pushes lists of frames into the EDMA TX
FIFO, rather than a single frame at a time.  The CABQ code already
pushes frame lists, but it turns out we should actually be doing it
in general or performance tanks. :(
