Parav Pandit 986994a275 nvme: Use CNS as 8-bit field and avoid endianness conversion
This patch defines CNS field as 8-bit field and avoids cpu_to/from_le
conversions.
Also initialize nvme_command cns value explicitly to NVME_ID_CNS_NS
for readability (don't rely on the fact that NVME_ID_CNS_NS = 0).

Christoph Hellwig a446c0840e nvme.h: resync with nvme-cli
Import a few updates to nvme.h from nvme-cli.  This mostly includes a few
new fields and error codes, but also a few renames that so far are only
used in user space.  Also one field is moved from an array of two le64
values to one of 16 u8 values so that we can more easily access it.

Christoph Hellwig a07b4970f4 nvmet: add a generic NVMe target
This patch introduces a implementation of NVMe subsystems,
controllers and discovery service which allows to export
NVMe namespaces across fabrics such as Ethernet, FC etc.

The implementation conforms to the NVMe 1.2.1 specification
and interoperates with NVMe over fabrics host implementations.

Configuration works using configfs, and is best performed using
the nvmetcli tool from http://git.infradead.org/users/hch/nvmetcli.git,
which also has a detailed explanation of the required steps in the
README file.
