kernel: add kmod-ipvlan support

This kmod is similar to macvlan with the difference being that the
endpoints have the same mac address.

It is useful on cloud where only one mac address allowed on port,
where macvlan not works but ipvlan would.

One use case is where multiple IPs and gateways assign on one net port
