Wireshark dissector for NGP

This is something we wanted to do a long time ago. But now we needed it … a wireshark dissector for the Eclipse SCADA NGP protocol stack. You can get the source from github (ctron/eclipse-scada-ngp-dissector).

Due to the complexity of the NGP protocol stack, we were only able to implement to message channel layer of the protocol. Also the streaming compression and SSL/TLS are not supported at the moment. But on the bright side it can handle TCP fragmentation and multiple packets in one TCP packet. Hopefully we can extend it a little bit in the future. For the moment it is a good start.
