/**
 * The PROTOCOL IDENTIFIER field is part of IDENTIFICATION DESCRIPTORS and may
 * indicate the SCSI transport protocol to which the identification descriptor
 * applies. If the ASSOCIATION field contains a value other than 01b (i.e.,
 * target port) or 10b (i.e., SCSI target device) or the PIV bit is set to zero,
 * then the PROTOCOL IDENTIFIER field contents are reserved. If the ASSOCIATION
 * field contains a value of 01b or 10b and the PIV bit is set to one, then the
 * PROTOCOL IDENTIFIER field shall contain one of the values defined in the
 * following table to indicate the SCSI transport protocol to which the
 * identification descriptor applies.
