And if you forgot to create /etc/udev/rules.d/75-persistent-net-generator.rules
and have rebooted with your new network card installed, you may have another
option. If you only have a single network card, just delete
/etc/udev/rules.d/70-persistent-net.rules and reboot. It will be re-created
with your single network card defined as eth0.
