  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
  25           need libibumad from rdma-core
  26           <https://github.com/linux-rdma/rdma-core>.

  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>.

  44           IOCTL based uAPI support for Infiniband is enabled by default for
  45           new verbs only. This allows userspace to invoke the IOCTL based uAPI
  46           for current legacy verbs too.

  60           On demand paging support for the InfiniBand subsystem.
  61           Together with driver support this allows registration of
  62           memory regions without pinning their pages, fetching the
  63           pages on demand instead.

  78           ConfigFS support for RDMA communication manager (CM).
  79           This allows the user to config the default GID type that the CM
  80           uses for each device, when initiaing new connections.
