| The NVM Express driver is for solid state drives directly |
| connected to the PCI or PCI Express bus. If you know you |
| don't have one of these, it is safe to answer N. |

| To compile this driver as a module, choose M here: the |

| This adds support for the SG_IO ioctl on the NVMe character |
| and block devices nodes, as well as a translation for a small |
| number of selected SCSI commands to NVMe commands to the NVMe |
| driver. If you don't know what this means you probably want |
| to say N here, unless you run a distro that abuses the SCSI |
| emulation to provide stable device names for mount by id, like |
| some OpenSuSE and SLES versions. |

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