  10           The NVM Express driver is for solid state drives directly
  11           connected to the PCI or PCI Express bus.  If you know you
  12           don't have one of these, it is safe to answer N.

  14           To compile this driver as a module, choose M here: the
  15           module will be called nvme.

  21            This option enables support for multipath access to NVMe
  22            subsystems.  If this option is enabled only a single
  23            /dev/nvmeXnY device will show up for each NVMe namespaces,
  24            even if it is accessible through multiple controllers.

  36           This provides support for the NVMe over Fabrics protocol using
  37           the RDMA (Infiniband, RoCE, iWarp) transport.  This allows you
  38           to use remote block devices exported using the NVMe protocol set.

  40           To configure a NVMe over Fabrics controller use the nvme-cli tool
  41           from https://github.com/linux-nvme/nvme-cli.
