Look in /etc/udev/rules/70-persistent-net.rules (might be different on 
debian). It probably has a rule to set the device name based on the mac 
detected, this can be removed if it's a problem for you. The device 
probably came up as eth1 or eth2. If you simply remove the entire line, 
it will be recreated, albeit with the mac detected on that boot, to 
change it permanently, you need to edit the line to NOT do the mac 
lookup, I don't recall how I've done that before, but I remember it was 
simple.
