RDMA/mad: Reduce MAD scope to mlx5_ib only
Management Datagram Interface (MAD) is applicable only when physical port is Infiniband. It makes MAD command logic to be completely unrelated to eth/core parts of mlx5. Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Acked-by: Jason Gunthorpe <jgg@mellanox.com>
