Help text

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.
