Wireshark · Ethereal-dev: [Ethereal-dev] Finding out if packet is plain UDP in tap listener

["Lars Ruoff" <lars.ruoff@xxxxxxxxxxxxxxxxxx>]

Hi,
Let's say i have a tap-listener that's called for every UDP packet (with
appropriate filter).
Is there a way of finding out in the tap-listener function, if the packet is
plain UDP (i.e. not dissected by any other dissector on top of UDP) ? How to
do?

Thanks,
Lars.
