Hello,

Is there a way to distinguish multiple frames of the same protocol in one TCP/IP packet? I have several small AMQP frames which all fit into a single IP frame, so they share a single packet_info structure.When I call p_add_proto_data() for the second AMQP frame, it (obviously) overwrites data stored for the first frame, so I need to distibguish between them somehow.

Is there a counter that would tell me "this is a third AMQP frame in this pinfo"? I found packet_info->curr_layer_num, but this is useful for nested frames (like IP in IP). Is there something similar for groupped frames, please?

Hi Peter,

I'm not sure we have such counter, but https://code.wireshark.org/review/#/c/10579/ suggested the use of tvb_raw_offset as key for p_(add|get)_proto_data() functions which seems a good tradeoff.

Best regards,

Pascal.
