Wireshark · Wireshark-dev: [Wireshark-dev] "Decode As" - adding payload decoding for the FLIP protocol

[Juha Siltanen <jsiltane@xxxxxxxxx>]

Hello,

The FLIP protocol (implemented in packet-flip.c) works on top of Ethernet, having type 0x8901 and adding its own headers plus payload. The FLIP headers contain no indication of the payload type and it cannot be deduced from the contents of the capture either. I would like to give the user an option to decode the payload to the protocol of his choosing by using "Decode As". The problem is that right-clicking and choosing "Decode As" only gives link-level protocols, and I would like to decode the payload using transport-level protocols (for example RTP).

So, how do I add the "Transport" tab into "Decode As" for FLIP, and how do I add RTP into the possible choices? Which files should I read to enlighten myself?

BR,
  Juha Siltanen
