eth<x> is the symbolic name assigned by the kernel to the Ethernet interface.
With PCI, an interface that is eth0 in a singly homed machine can become eth1
when a second interface is to the machine. This effect is due to the order
in which the cards are found during the boot up sequence. Probes can run
high to low, or low to high. This is a software decision that may not be
open for change - but it's worth a look-see in the BIOS. You may want to try
swapping the card positions in your machine to gauge the effect, for example,
will card A become eth0 in a machine where it is 1 of 1 Ethernet IF and 1 of
2 Ethernet IF? Another approach is to accept the eth<x> names assigned to
the cards by the system and then "ifconfig" them to match the appropriate net
address for you network.
