+ Userspace InfiniBand Management Datagram (MAD) support. This

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