8	---help---
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.

16config NVME_MULTIPATH
17	bool "NVMe multipath support"
18	depends on NVME_CORE
19	---help---
20	   This option enables support for multipath access to NVMe
21	   subsystems.  If this option is enabled only a single
22	   /dev/nvmeXnY device will show up for each NVMe namespaces,
23	   even if it is accessible through multiple controllers.

33	select SG_POOL
34	help
35	  This provides support for the NVMe over Fabrics protocol using
36	  the RDMA (Infiniband, RoCE, iWarp) transport.  This allows you
37	  to use remote block devices exported using the NVMe protocol set.
38
39	  To configure a NVMe over Fabrics controller use the nvme-cli tool
40	  from https://github.com/linux-nvme/nvme-cli.
41
42	  If unsure, say N.

52	  This provides support for the NVMe over Fabrics protocol using
53	  the FC transport.  This allows you to use remote block devices
54	  exported using the NVMe protocol set.

67	  This provides support for the NVMe over Fabrics protocol using
68	  the TCP transport.  This allows you to use remote block devices
69	  exported using the NVMe protocol set.
