0023 is the kernel side of the userspace MAD support, which allows

0032 Userspace InfiniBand access support. This enables the
0033 kernel side of userspace verbs and the userspace
0034 communication manager (CM). This allows userspace processes
0035 to set up connections and directly access InfiniBand
0036 hardware for fast-path operations. You will also need
0037 libibverbs, libibcm and a hardware driver library from
0038 rdma-core <https://github.com/linux-rdma/rdma-core>.
