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.
