This enabled target side support for the NVMe protocol, that is
|
it allows the Linux kernel to implement NVMe subsystems and
|
controllers and export Linux block devices as NVMe namespaces.
|
You need to select at least one of the transports below to make this
|
functionality useful.
|
|
To configure the NVMe target you probably want to use the nvmetcli
|
tool from http://git.infradead.org/users/hch/nvmetcli.git.

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

side, incuding executing Vendor Unique Commands.
