32	  Userspace InfiniBand access support.  This enables the
33	  kernel side of userspace verbs and the userspace
34	  communication manager (CM).  This allows userspace processes
35	  to set up connections and directly access InfiniBand
36	  hardware for fast-path operations.  You will also need
37	  libibverbs, libibcm and a hardware driver library from
38	  rdma-core <https://github.com/linux-rdma/rdma-core>.
