  /*
   * Some Notes on using the SCSI Decoder:
   *
   * The SCSI decoder has been built right now so that it is invoked directly by the
   * SCSI transport layers as compared to the standard mechanism of being invoked
   * via a dissector chain. There are multiple reasons for this:
   * - The SCSI CDB is typically embedded inside the transport along with other
   *   header fields that have nothing to do with SCSI. So, it is required to be
   *   done this way.
   * - Originally, Wireshark couldn't do filtering on protocol trees that were not
   *   on the top level.
   *
   * There are four main routines that are provided:
   * o dissect_scsi_cdb - invoked on receiving a SCSI Command
   *   void dissect_scsi_cdb(tvbuff_t *, packet_info *, proto_tree *,
   *                         guint, itlq_nexus_t *, itl_nexus_t *);
   * o dissect_scsi_payload - invoked to decode SCSI responses
   *   void dissect_scsi_payload(tvbuff_t *, packet_info *, proto_tree *, guint,
   *                             gboolean, itlq_nexusu_t *, itl_nexus_t *,
   *                             guint32 relative_offset);
   *   The final parameter is the length of the response field that is negotiated
   *   as part of the SCSI transport layer. If this is not tracked by the
   *   transport, it can be set to 0.
   * o dissect_scsi_rsp - invoked to dissect the scsi status code in a response
   *                      SCSI task.
   *   void dissect_scsi_rsp(tvbuff_t *, packet_info *, proto_tree *,
   *                         itlq_nexus_t *, itl_nexus_t *, guint8);
   * o dissect_scsi_snsinfo - invoked to decode the sense data provided in case of
   *                          an error.
   *   void dissect_scsi_snsinfo(tvbuff_t *, packet_info *, proto_tree *, guint,
   *                             guint, itlq_nexus_t *, itl_nexus_t *);
   *
   * In addition to this, the other requirement made from the transport is to
   * provide ITL and ITLQ structures that are persistent.
   *
   * The ITL structure uniquely identifies a Initiator/Target/Lun combination
   * and is among other things used to keep track of the device type for a
   * specific LUN.
   *
   * The ITLQ structure uniquely identifies a specific scsi task and is used to
   * keep track of OPCODEs between CDB/DATA/Responses and resp[onse times.
   *
   * This decoder attempts to track the type of SCSI device based on the response
   * to the Inquiry command. If the trace does not contain an Inquiry command,
   * the decoding of the commands is done as per a user preference. Currently,
   * only SBC (disks) and SSC (tapes) are the alternatives offered. The basic
   * SCSI command set (SPC-2/3) is decoded for all SCSI devices. If there is a
   * mixture of devices in the trace, some with Inquiry response and some
   * without, the user preference is used only for those devices whose type the
   * decoder has not been able to determine.
