Thanks for tackling this cluster$%@#.  I'm not crazy about the 
CONFIG_NET_MULTI_MAX, but then I'm not really sure why the ethernet 
addresses exist in global data on boards with CONFIG_NET_MULTI.  The net 
library doesn't use them, most (maybe all?) of the drivers don't look at 
it.  Some common code does, but does it need to?  Maybe it's needed to 
pass to some operating systems?  This is an example of something that 
could use some serious refactoring, but I expect it's an onion with 
many, many layers.  OTOH, if you're going to change the name of a 
variable in global data, you'll find out really fast where it's used.  
Maybe we can gut it completely?  I'm lacking in historical perspective 
and my world view is pretty limited, so hopefully others (read WD) will 
chime in.

Ben
