| 9 | The NVM Express driver is for solid state drives directly |
| 10 | connected to the PCI or PCI Express bus. If you know you |
| 11 | don't have one of these, it is safe to answer N. |
| 12 | |
| 13 | To compile this driver as a module, choose M here: the |
| 14 | module will be called nvme. |

| 26 | This provides support for the NVMe over Fabrics protocol using |
| 27 | the RDMA (Infiniband, RoCE, iWarp) transport. This allows you |
| 28 | to use remote block devices exported using the NVMe protocol set. |
| 29 | |
| 30 | To configure a NVMe over Fabrics controller use the nvme-cli tool |
| 31 | from https://github.com/linux-nvme/nvme-cli. |
| 32 | |
| 33 | If unsure, say N. |
