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

userspace processes to send and receive MADs. You will also

Userspace InfiniBand access support. This enables the

kernel side of userspace verbs and the userspace

communication manager (CM). This allows userspace processes

hardware for fast-path operations. You will also need

rdma-core <https://github.com/linux-rdma/rdma-core>.
