I ISTR reading somewhere that Suns have one MAC address in the ID-PROM
and another (unique) one in each ethernet and FDDI adaptor.  By default,
all the interfaces use the ID-PROM address, but AFAIR there used to be
some option to ifconfig under SunOS 4 which would show you the adaptor's
MAC address, and let you use that instead.
