In this same vein, I need to assign a virtual interface to my 3Com NIC in
an x86 Solaris box on the same network as the primary interface.  First,
there wasn't a local-mac-address variable set at all per eeprom - I set it
anyway.  I can create secondary interfaces, but the ifconfig ether option
won't accept alternate MAC addresses.  Just for the hell of it I created a
secondary and addressed it with another IP on the same network.  It
doesn't seem to be freaking out, but for the life of me I don't understand
why.
