No, welcome to the world of workstations. MAC addresses
ONLY started appearing on cards for computers that were
never expected to be on networks (mainly PCs). Suns (and
most other workstations) have a Mac address assigned TO
THE MACHINE. When there is no Mac address assigned to
the machine (ala PC), the card must have one.

Generally, it's a bad notion to put two network interfaces
onto the same network (see, it's got one interface already,
why would you put two?)

In SunOS (4, 5, maybe 3), you can say "ifconfig leN ether 8:0:20:1:2:3"
and it will assign. There's a C snippet around from Dug Sung that does
the same thing. (sea.c?)
