22 Userspace InfiniBand Management Datagram (MAD) support. This
23 is the kernel side of the userspace MAD support, which allows
24 userspace processes to send and receive MADs. You will also

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>.
