Hello all,
 
here is a small patch for the flow graph feature. It allows to have SS7
nodes (network indicator/point codes) to be recognized as nodes in the
graphs.
The patch consists in using "pinfo->net_src" or "pinfo->net_dst" instead
of "pinfo->src" or "pinfo->dst".
I did some tests with other IP protocols and behavior was still the same
as before. But I do not guaranty that it doesn't have some bad side
effects for some protocols.

Here is a sample dialog between two SS7 point codes: 514 and 257
(network indicator: 2 (national):
