ipip: convert to net_device_ops
Convert to network device ops. Needed to change to directly call the init routine since two sides share same ops. In the process found by inspection a device ref count leak if register_netdevice failed. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: David S. Miller <davem@davemloft.net>
