| 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, including executing Vendor Unique Commands. | |
