Now days, when Fedora detects a different NIC from one it knew (right or 
wrong), it creates a new entry in: /etc/udev/rules.d/70-persistent-net.rules

This is why you get messages in dmesg and at bootup that eth0 is being 
'moved' to eth1.

It is reasonably safe to remove this file, plus 
/etc/sysconfig/network-scripts/ifcfg-eth? and reboot.

If you are just doing DHCP, then udev will recreate the file, put the 
correct NIC into it, and set up a generic ifcfg-eth0 script.

Good luck!
