+/*
+ * Some Notes on using the SCSI Decoder:
+ *
+ * The SCSI decoder has been built right now 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 alongwith other
+ * header fields that have nothing to do with SCSI. So, it is required to be
+ * invoked on a embedded subset of the packet.
+ * - Originally, Ethereal 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,
+ * guint);
+ * o dissect_scsi_payload - invoked to decode SCSI responses
+ * void dissect_scsi_payload (tvbuff_t *, packet_info *, proto_tree *, guint,
+ * gboolean, guint32);
+ * 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 destroy the data structures associated with a
+ * SCSI task.
+ * void dissect_scsi_rsp (tvbuff_t *, packet_info *, proto_tree *);
+ * 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);
+ *
+ * In addition to this, the other requirement made from the transport is to
+ * provide a unique way to determine a SCSI task. In Fibre channel networks,
+ * this is the exchange ID pair alongwith the source/destination addresses; in
+ * iSCSI it is the initiator task tag along with the src/dst address and port
+ * numbers. This is to be provided to the SCSI decoder via the private_data
+ * field in the packet_info data structure. The private_data field is treated
+ * as a 32-bit field to uniquely identify a SCSI task.
+ *
+ * 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.
