Dear Guy, Dear all,

using the sctp dissector would like be able to filter packets with
wrong checksum in it.

Currently I'm calculating the checksum in the dissector and display it
with proto_tree_add_uint_format. I'm trying also to insert in the tree
a boolean variable with proto_tree_add_item (or the hidden version) and
provide a boolean variable as a parameter, which describes oof the checksum is right. But this bit is not part of the packet, of course. How can I do it? I think it is quite helpful to be able to search for such 'computed' information.

Any hints are welcome.
Thank you in advance
Michael
