NVMe SCSI support

[Panah, Khosrow]

I noticed there is a development in process to support NVMe SCSI interface. Can anyone clarify as why Intel is supporting SCSI interface?
I have not been able to pull NVMe SCSI driver from Intel site. When I pull the latest driver, I get a driver that does not include support for "sg_ioctl". I would greatly appreciate if you could point me to where I can gain access to the source that includes above source version.

Thank you,
