Two Identical PCI NICs, how to choose which is eth0 and which is eth1

[Aaron Grewell]

Figure out which PCI slots are which (each has a number), then try
assigning IRQ's to each of your NIC slots and see if a higher or lower
IRQ affects the ordering of the ETH settings.  I've never tried to
actually specify which is which, but that's how I would try to do it.
