MAC is technically per system if desired (eg old Sun boxes) and that is
quite valid by IEE802.3. In that case you need MAC + topology.

If you are running DECnet your system runs on assigned MAC addresses so
you also have to be careful to use the EPROM MAC (if one exists which is
99.9% of the time) + topology.

I'd argue the fumdamental problem is that I can do this

	ln -s /dev/sda /dev/thebigdiskunderthefridge

but cannot ln -s /dev/eth0 /dev/ethernet/slot0

and the SIOCGIF/SIF BSD style ioctl interface doesn't do pathnames or
file handles of network devices.

Anyone feel up to putting all the network devices into dev space and
fixing the ioctls ;)
