23 Userspace InfiniBand Management Datagram (MAD) support. This
24 is the kernel side of the userspace MAD support, which allows
25 userspace processes to send and receive MADs. You will also
26 need libibumad from rdma-core

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