So the operations staff that will do the swap are expected to have a
table of the physical location of each NIC and the corresponding MAC
for the old box and the new replacement?   That's not entirely
unreasonable, but it would be nice if it could be made easier.   And I
think the way udev works in RHEL 6.x you could map the pci location to
the name,  then the name would stick to the config file if you knock
out the HWADDR or pick up the correct value and replace it.   There is
also a scheme that works with the bios names for the NICs to deal with
this specific issue, but currently only for certain Dell models.
