0010 This enabled target side support for the NVMe protocol, that is
0011 it allows the Linux kernel to implement NVMe subsystems and
0012 controllers and export Linux block devices as NVMe namespaces.
0013 You need to select at least one of the transports below to make this
0014 functionality useful.

0016 To configure the NVMe target you probably want to use the nvmetcli
0017 tool from http://git.infradead.org/users/hch/nvmetcli.git.

0024 This enables target side NVMe passthru controller support for the
0025 NVMe Over Fabrics protocol. It allows for hosts to manage and
0026 directly access an actual NVMe controller residing on the target
