  10           This enabled target side support for the NVMe protocol, that is
  11           it allows the Linux kernel to implement NVMe subsystems and
  12           controllers and export Linux block devices as NVMe namespaces.
  13           You need to select at least one of the transports below to make this
  14           functionality useful.

  16           To configure the NVMe target you probably want to use the nvmetcli
  17           tool from http://git.infradead.org/users/hch/nvmetcli.git.

  24           This enables target side NVMe passthru controller support for the
  25           NVMe Over Fabrics protocol. It allows for hosts to manage and
  26           directly access an actual NVMe controller residing on the target
  27           side, incuding executing Vendor Unique Commands.
