Fortunately, the SCSI definition includes a length field. As a
result, you can simply use length field and the identifier of 3
to specify that the format is FC-PH, but that the length is 16 bytes.
The FC-PH NAA then defines for you the precise format of those
The length field is properly defined in the SPC document, but in
some parts of the document is mis-named "page length".
For reference, see SPC rev 11, page 125, table 109, byte 3.
