This patch is to enable the use of scsi_id to derive a UID for a SCSI-2 device which is not compliant with the page 83 inquiry reply format for either SPC-2 or SPC-3. In this case, the page 83 reply does not contain a list of Identification descriptors but a single binary encoded hexa-decimal Vendor Specified Identifier. The update is being driven by the need for scsi_id to support older model EMC Symmetrix hardware, that is, models 4, 5, and 6.
