Sure, in this case it's an ethernet.  But FDDI also uses 48 bit MAC
addresses.  Would you use the same IOCTL to provide physical layer addresses
for other sorts of interfaces?  Firewire uses (I think) 64 bit MAC
addresses. 802.11 use 48 bit addresses on their MAC, though most
folks think and treat them like Ethernet interfaces.  

This is an instance of a general problem, and all the world is
not a VAX, er, ethernet.
