/*
 * 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.
