That would confuse ifcfg-* scripts that specify HWETHER, and probably
users as well. It might even stump udev.

An "ifconfig ethX hw ether xx:xx:xx:xx:xx:xx" in network scripts allows
udev to use the consistent "bad" MAC to assign a consistent ethX number,
and allows the networking scripts to use the consistent "new good" MAC.
It works as a stand-alone interface, as a WAN port hosting ppp0, and
even in bonding, all consistently.
