I run a machine as a bridge between two ethernet interfaces, one of which
has an IP address assigned (OK, it has an alias IP too).  It just works.
Also, because it's a sparc, the two interfaces have the same ethernet (MAC)
address.  But that doesn't matter, as the MAC address(es) of the bridge are
not relevant when bridging traffic.
