This module is a work in progress, but is designed mainly to allow the user to give persistent names to interfaces based on their MAC address (in the future alternative methods might be provided).
The udevnet::interface type takes the new interface name as name and
the MAC address as the hwaddress parameter:
udevnet::interface { 'wan0':
hwaddress => 'ff:de:ad:be:ef:00',
}
The define will remove 70persistent-net.rules if present and will
make sure to link 80net-slot-name.rules to /dev/null to make sure
that the new "predictable" names are not used.
