Wireshark-dev: Re: [Wireshark-dev] How to find duplicate packets with time interval less than 2

The issue there is that you'll need a buffer whose size is
indeterminate (you can get way more than 4 packets in 2ms).

So the buffer should adjust.

BTW if you add a parameter for the time window it would be certainly
more useful.
