* Mpt3sas driver uses the NVMe Encapsulated Request message to send an
  NVMe command to an NVMe device attached to the IOC.

* Normal I/O commands like reads and writes are passed to the
  controller as SCSI commands and the controller has the ability to
  translate the commands to NVMe equivalent.

* This encapsulated NVMe command is used by applications to send
  direct NVMe commands to NVMe drives.
