// There are multiple different ways to add functionality based on CIP class-specific behavior:
// 1. Dissector Table "cip.io.iface" - Use this when Class 0/1 I/O needs different parsing based on
// the CIP Class in the Forward Open
// 2. Dissector Table "cip.connection.class" - Use this when Class 2/3 data needs different parsing
// based on the CIP Class in the Forward Open
// 3. Dissector Table "cip.class.iface" - Use this when a CIP Class has significantly different
// behavior that would be best handled through a separate dissector
// 4. Dissector Table "cip.data_segment.iface" - Unknown. This may be removed in the future
// 5. attribute_info_t: Use this to add handling for an attribute, using a 3 tuple key (Class, Instance, Attribute)
// See 'cip_attribute_vals' for an example.
// 6. cip_service_info_t: Use this to add handling for a service, using a 2 tuple key (Class, Service)
// See 'cip_obj_spec_service_table' for an example.
