Re: physical network port matchup to /etc/sysconfig/network-scripts/ifcfg-eth*

I'll usually find out what the MAC addresses of the ports are (usually from
a sticker on the case somewhere, or on the card), and then from there you
should be able to either compare and match the MAC address as listed in your
ifcfg files (via the HWADDR variable), or, if the ifcfg files don't have it,
you can look at the output of dmesg to determine which interfaces are going
with which MACs as well.

Hope that helps as a way to throw a couple options out there!
