Hi,

I was testing pcapparse on some capture of a Panasonic GH3 camera (the video
data is some MJPEG over UDP variant BTW):
wget
http://www.personal-view.com/talks/uploads/FileUpload/03/24c6c8d18eb6ca40775e1438464147.jpg
-O LumixLink_captureStill.pcap

The Wireshark filter to see the interesting data is: "udp.srcport == 65416"

I didn't understand why, when specifying the src-port, no data was getting
downstream. After adding some printouts and looking again at the wireshark logs
I finally figured out it was because pcapparse cannot parse fragmented IP
packets.

So what about adding an explicit check for this and warn the user with an
error?

I will propose a patch for that, along with some comments which may help
readers new to pcapparse code.

Ciao,
   Antonio
