I need to plot a cumulative byte-length graph with IO Graphs,
therefore I'm planning to develop this extension.
I'm not familiar with Wireshark development, so I ask for a little bit
of support to you.
In the "frame_data" structure in epan/frame_data.h there's the
cum_bytes value. Is this value regularly updated or the field is just
a placeholder for a feature development?
Stig says "it's just a matter of adding this as a generated frame
field"; what does it mean?
In dissectors/packet-frame.c there are no references to the cum_bytes
value. Do I need to add in dissect_frame something like:
proto_tree_add_uint_format(fh_tree, hf_frame_cum_len, tvb
0, 0, cum_len, "foo bar", cum_len,
plurality(cum_len, "", "s"));
Can you please suggest me the other required changes?
Thanks for your help.
