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

  32           kernel side of userspace verbs and the userspace
  33           communication manager (CM).  This allows userspace processes
  34           to set up connections and directly access InfiniBand
  35           hardware for fast-path operations.  You will also need
  36           libibverbs, libibcm and a hardware driver library from
  37           rdma-core <https://github.com/linux-rdma/rdma-core>.

  44           The UCM module has known security flaws, which no one is
  45           interested to fix. The user-space part of this code was
  46           dropped from the upstream a long time ago.

  48           This option is DEPRECATED and planned to be removed.

  54           IOCTL based uAPI support for Infiniband is enabled by default for
  55           new verbs only. This allows userspace to invoke the IOCTL based uAPI

  70           On demand paging support for the InfiniBand subsystem.
  71           Together with driver support this allows registration of
  72           memory regions without pinning their pages, fetching the
  73           pages on demand instead.

  90           uses for each device, when initiaing new connections.
