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.
config NVME_TARGET_DEBUGFS
bool "NVMe Target debugfs support"
depends on NVME_TARGET
help
This enables debugfs support to display the connected controllers
to each subsystem
If unsure, say N.

bool "NVMe Target Passthrough support"
depends on NVME_TARGET
depends on NVME_CORE=y || NVME_CORE=NVME_TARGET
help
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, including executing Vendor Unique Commands.
If unsure, say N.

help
This enables the NVMe loopback device support, which can be useful
to test NVMe host and target side features.
If unsure, say N.

This enables the NVMe TCP target support, which allows exporting NVMe
devices over TCP.
If unsure, say N.
config NVME_TARGET_TCP_TLS
bool "NVMe over Fabrics TCP target TLS encryption support"
depends on NVME_TARGET_TCP
select NET_HANDSHAKE
help
Enables TLS encryption for the NVMe TCP target using the netlink handshake API.
The TLS handshake daemon is available at
https://github.com/oracle/ktls-utils.
If unsure, say N.
config NVME_TARGET_AUTH
