You need to do better than this.. rdma-core should setup to detect
which of the kernel drivers is present and do the right thing. This
may require some new infrastructure work, but siw and rxe need this
capability as well.

Be aware we cannot take net-next into rdma. You would be best to
submit a clean -rcX based PR to both net and RDMA for your net
portion.
