 * SCSI inquiry properties.  The following properties figuratively
 * represent 'inquiry' data.  Some of the values may be more detailed
 * (longer in length) than the basic 'struct scsi_inquiry' fields. For
 * example the INQUIRY_REVISION_ID field in 'struct scsi_inquiry' is
 * four bytes long, but SATA's 'Identify Device Data' is eight bytes.
 * In situations like this an HBA driver's tran_tgt_init(9E)
 * implementation may establish different, more detailed, values than
 * those returned by 'struct scsi_inquiry'.  In addition some
 * properties like 'serial number' and 'capacity' are never derived
 * from 'struct scsi_inquiry'.  Instead, the information is obtained
 * from an INQUIRY command to another page (page 0x80 for serial
 * number), by some other SCSI commands (like READ_CAPACITY for
 * capacity), or by some HBA driver specific mechanism.
