Are you trying to change the message structure from that of OpenFlow Spec? If so, Ryu will try to parse the packet as OpenFlow Spec structure, then Ryu may assume it malformed. If you want to parse your original structured packets, you need to modify the following class. https://github.com/osrg/ryu/blob/master/ryu/ofproto/ofproto_v1_3_parser.py#L4184-L4195 or... Your implementation is diverged from OpenFlow Spec, I think it better to use "Experimenter Multipart" messages instead.
