I was suggesting the VPD because that may be easier for the SAS HBA
vendors to accommodate for SATA passthrough. But we can cross that
bridge when we get to it.

For libata I'm fine with keying off a supports_opal:1 flag in
scsi_device or something to that effect. I'd just like to reduce the
risk of introducing more RSOC regressions.
