I think someone just needs to write device-indenpendent support and then
modify various drivers.

I don't think the tap's Ethernet address is relevant.  The PDP-10's
emulated Ethernet interface (how modern to plug one of those in, instead
of CHAOSnet or an IMP....) will have an address, but that's controlled
entirely within the emulator.  Packets with that source address are
generated, and then written to /dev/tapN to make them show up on the
virtual interface on the host.
