The Standard Inquiry Data is based on the SCSI 3 standard for Standard Inquiry
Data. This allows for setting certain bits in byte 6 to indicate features that were non-
standard in SCSI 2. The only supported SCSI 3 field is Multi Port (MultiP).
The Multi-Port (MultiP) flag is set if the device has multiple interface ports. Parallel
SCSI devices will not have multiple interface ports and will have this flag clear. Fibre
Channel devices will have multiple interface ports and will have this flag set.
The 16 Bit Address (Adr16) and Wide Bus 16 (WBs16) flags are set depending on
whether the hardware supports these bus features. These flags are only valid for
parallel SCSI and are clear for all other low level interfaces.
