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, including executing Vendor Unique Commands.
