Hi Vikas, the ZPU dissector shouldn't help you (IIRC, there's no DUDEBRO protocol between host and B2xx). However, yes, the RFNoC dissector is what has become of the CHDR dissector.
When I look at your screenshot, it looks to me as if Wireshark wasn't told to actually decode the packets as RFNoC. Could you try right click -> Decode as... and try that?
