As I wrote, just edit this file to match your current interfaces. The 
easiest way to do it is just delete the line that ends with eth0, and 
change eth1 to eth0. When you reboot, the interface with mac 
00:16:3e:00:00:d5 will then appear at eth0.
All this file does is store persistently the mappings generated when 
udev finds a new device - a big improvement from the days when the 
interfaces could change names/order under different OSs, or even 
randomly at boot time :( The downside is that you may need to go and 
manually delete/edit mappings when changing 'hardware'.
