Re-Order Nic Cards

There are a couple ways.

The brute force way is to physically remove all NICs, reboot, and allow Kudzu to 
remove configs for all three. Then reinstall the cards, allow Kudzu to 
reconfigure the cards, and enter the correct IP addresses, etc.

The better way is to edit the ifcfg-ethx files which are located in 
/etc/sysconfig/network-scripts/. The sample (filename = ifcfg-eth0) below shows 
what I am talking about.

# Realtek|RTL-8139/8139C/8139C+

Backup all the  /etc/sysconfig/network-scripts/ifcfg-ethx scripts. Stop all 
devices with ifdown, or stop the network service. Change the device line and the 
file name of each of these files to match what you want. For example if you want 
this device to be eth2, change the filename to ifcfg-eth2, and the device line 
to DEVICE=eth2.

Then restart the network, or the individual devices using ifup.

That should take care of it.
