In many cases, the protocol can customize or specify the port number instead of using the fixed allocation on the RFC. After I read the code of the TCP and UDP layer of PcapPlusPlus, I found that PcapPlusPlus is always recognized based on the default port number on the RFC. This is not flexible enough and scalability is not strong in many application scenarios. Do we have plans to add this kind of custom parsing in the future? If a custom parsing method is specified in the configuration file, the custom method will be used first, otherwise The default RFC-based port is still used for resolution.
