Thanks! It looks much better than my patch and works as I expected. I
also appreciate Ronnie for giving me a lot of good advises.

I personally think it is unlikely for an LDP PDU to span multilple TCP
segments. If I come across such a case, I will then add a
desegmentation support to the LDP dissector.

Best Regards,
