The name of a physical interface is determined by lower levels of the
operating system, and can't be modified by netcf. the configuration that
is setup by netcf can only reference an *existing* physical device name,
it can't rename it.

One source of information is here:
http://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames/
(although that only completely applies to systems running recent
systemd, e.g. Fedora 20, but not to RHEL6 as you appear to be running)
There is a reference there of how to change an interface name in a
system that isn't using "predictable network interface names" (or
biosdevname, which was a short-lived alternative attempt at a solution
to the same problem): modify the file
/etc/udev/rules.d/70-persistent-net.rules. You'll need to reboot the
system for this to take effect.
