Yes, it should be like that. It's just the way Suns work. They change
the MAC address of all Ethernet interfaces to be the same as the 
"primary" interface (typically le0). It's OK, because MAC addresses only
really have to be unique on a per-segment basis for things to work, and
it keeps a 1-to-1 relationship between machines and MAC addresses.
