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