So where does that information come from?
If it's something your dissector calculates based on data from the packet, or based on information it's saved from previous packets, or something such as that, you should just use one of the other proto_tree_add_ routines and directly pass that value to the routine, rather than adding it to a tvbuff and using proto_tree_add_item().
