Wireshark · Wireshark-dev: [Wireshark-dev] Unexpected tap behaviour

[Anders Broman <a.broman@xxxxxxxxxxxx>]

Hi,
I just implemented the export_pdu tap for Diameter as well as SIP to my 
surprise if I don't define
a filter only SIP packets get experted from a file with both Diameter 
and SIP. If I specify a filter of
"diameter or SIP" both gets exported. I would have expected both to be 
exported with no filter. Could any one shed
some light on what's going on?
Regards
Anders
