I know this is systemd-punching day, but at least get your information
straight.

Unrelated to systemd, as far as I can tell.  Fedora adopted new names
that made more sense, and it was incorporated into RHEL7.

Unrelated to systemd.  This actually started happening in RHEL6 with
the biosdevname feature.  systemd can handle the NIC naming stuff, but
it started happening well before systemd appeared in RHEL.

Having consistent device names is helpful when you've got more than
one NIC and you don't want to rely on the order in which the network
driver is loaded to define the interface name.
