| 9 | The NVM Express driver is for solid state drives directly |
| 10 | connected to the PCI or PCI Express bus. If you know you |

| 13 | To compile this driver as a module, choose M here: the |
| 14 | module will be called nvme. |

| 38 | This provides support for the NVMe over Fabrics protocol using |
| 39 | the RDMA (Infiniband, RoCE, iWarp) transport. This allows you |
| 40 | to use remote block devices exported using the NVMe protocol set. |

| 42 | To configure a NVMe over Fabrics controller use the nvme-cli tool |
| 43 | from https://github.com/linux-nvme/nvme-cli. |
