I am using dumpcap to dump my network stream(network bandwidth is 200-500Mbps) to .cap files because it's low level and drop should be lessed but dumpcap does not report any drop statistics. I would like to know whether it has drop. Can Dumpcap report dropped statistics? I used libpcap 0.8.3 and wireshark 0.99.5 on Fedora core 4
At least with Wireshark 1.0.0 'dumpcap' does tell if you if it dropped 
some packets or not:
Packets: 36 Packets dropped: 0
(AFAIK the number of dropped packets is whatever the capture 
mechanism--libpcap or WinPCAP--tells it.)
