| 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. |
