* Different protocols (i.e. games) use different set of message IDs,
* and we can't infer protocols from message ID because there is no
* central registry. So the only thing we can do is to use port number
* or heuristics to determine the protocol.
*
* If your protocol has a fixed port number, you can register it with
* this function. The registered dissector will be called with a tvb
* buffer which contains a RakNet message including message ID at its
* first octet. Header analysis, packet reassembly, and RakNet system
* messages are all handled by the RakNet dissector so you don't need
* to worry about them.
