ibv_rc_pingpong runs over verbs and not RDMA_CM.
As far as I understood, RoCE requires the use of the RDMA CM (in open mpi),
and it is not possible to set explicitly the SL in RDMA_CM.
We should check if RDMA_CM is must for RoCE.

The attached example code (stripped down from a bigger app) demonstrates

to the call
MPI_Comm_create(MPI_COMM_WORLD, MPI_GROUP_EMPTY, &dummy_comm);
