[nSLUG] MAC-address/router question

to furthure muddy the waters:

Older Sun Sparc machines use a single MAC for all ethernet devices. I
belive all sun4/sun4m machines do this (e.g. SparcStations and
SparcServers). Durring POST the open firmware loads the system serial
number into the ethernet devices. IIRC you can configure the devices
to use different numbers and save the values in the nvram. Using a
system MAC instead of a per card MAC makes sense, especially back in
the day of netbooting. Admins don't want to change bootp, rarp, and
ethers config files everytime an ethernet card is replaced.
