nvme.h: add NVMe over Fabrics definitions
The NVMe over Fabrics specification defines a protocol interface and related extensions to NVMe that enable operation over network protocols. The NVMe over Fabrics specification has an NVMe Transport binding for each NVMe Transport. This patch adds the fabrics related definitions: - fabric specific command set and error codes - transport addressing and binding definitions - fabrics sgl extensions - controller identification fabrics enhancements - discovery log page definition Signed-off-by: Armen Baloyan <armenx.baloyan@intel.com> Signed-off-by: James Smart <james.smart@broadcom.com> Signed-off-by: Jay Freyensee <james.p.freyensee@intel.com> Signed-off-by: Ming Lin <ming.l@ssi.samsung.com> Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Keith Busch <keith.busch@intel.com> Signed-off-by: Jens Axboe <axboe@fb.com>
