Description
For UDPRecvV6 event, OpCode is the same as TCPRecvV6. I checked the SystemEvents.man, looks like for UDPRecvV6 event, the OpCode should be 59 instead.

Research direction
Start in src/TraceEvent/Parsers/KernelTraceEventParser.cs at line 1705 and compare the UDPRecvV6 mapping with the linked SystemEvents.man reference. Confirm the documented opcode and update the parser entry; the work is done when UDPRecvV6 uses the correct opcode.
