Hi list,

i'm working on a plugin to dissect a private protocol that use link aggregation. I have to produce stats for each link used. The problem is that the protocol doesn't provide any information about which link were used to send one packet. So I have to work with the source ip/port. Is there a way to retrieve those values from the UDP dissector ?


Have a look at the packet_info struct in epan/packet_info.h which is passed into every dissector.  The struct holds various source and destination addresses.
