[PATCH rdma-next V1 1/5] IB/core: Add raw packet protocol

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Or Gerlitz <ogerlitz-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

Define raw packet protocol which comes to denote this port supports
working with raw ethernet frames, e.g as done with RAW_PACKET QPs.
