I firmly maintain my opinion that if this is the only place the event 
numbers are referenced then the extra layer of macros actually makes it 
*harder* to read and follow, compared to simply:

	MAC_EVENT_ATTR(ea-ha, 0xa0),

but that is very much just one reviewer's personal opinion :)

I'll second this suggestion!  I failed to notice they were only used here.
