/*
* 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.
