[CLUG] network card id switching

You can define the Ethernet address in redhat (Fedora and EL) using the
/etc/sysconfig/network-scripts/ifcfg-ethX file, which contains the device's
mac address.

This binds that card designation to it's address. If you need to config
anythis else, you can use the "neat" config tool, or system-config-network.

If I understand correctly, it's actually possibly to bring up the
configuration of an interface (and, in fact, rename it if you're using
kernel 2.6 [with sysfs?]) according to its MAC address.
