Log:
  [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. :(
