Well, again, if you don't want to associate a port to this pci
resource, why are you registering a eth_driver ?
A eth_driver driver supposes you have a 1 - 1 relation between ethdev
and pci resource.

For your case, register a pci driver, then in your pci probing
function (.devinit), depending on what you want to do, you can either
do nothing (?) or create one or more ethdevs (see mlx* and cxgbe
drivers).
