FYI, Michał is first user of call_dissector_with_data[1][2]
His use of data argument is really simple, no strcture passing, just TRUE value or FALSE/NULL.

I'd prefer to only pass strctures (flexible, easy to maintain), with magic numbers on begin 
of structure + document every use in some doc/ file.

These rules might be too strict, and I don't want to enforce only my rules,
so how do we want to use data argument?
