I agree that that 'struct eth_driver' is not adding a lot now.
It should really be all folded back into 'struct rte_driver'.
The concept of init, uninit and private data are all generic and not
really specific to ethernet in anyway.
If we kill off eth_driver then PCI devices only have rte_pci_driver
and VMBUS can have rte_vmbus_driver.
