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

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

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

  35           This provides support for the NVMe over Fabrics protocol using
  36           the RDMA (Infiniband, RoCE, iWarp) transport.  This allows you
  37           to use remote block devices exported using the NVMe protocol set.
  38
  39           To configure a NVMe over Fabrics controller use the nvme-cli tool
  40           from https://github.com/linux-nvme/nvme-cli.

  42           If unsure, say N.

  52           This provides support for the NVMe over Fabrics protocol using
  53           the FC transport.  This allows you to use remote block devices
  54           exported using the NVMe protocol set.
