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

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

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

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

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