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

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

20 ---help---
21 This option enables support for multipath access to NVMe
22 subsystems. If this option is enabled only a single
23 /dev/nvmeXnY device will show up for each NVMe namespaces,
24 even if it is accessible through multiple controllers.

30 This provides support for NVMe hardware monitoring. If enabled,
31 a hardware monitoring device will be created for each NVMe drive
32 in the system.

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