Comment 20 for bug 1306705

I'm pretty sure now, that the problem is in python libpcap bindings, cause dumping traffic with tcpdump works for me, but
python-pcap misses a lot of packets.

Probably the reason tcpdump works good is that it does some preparation begind the scenes, like increasing queue buffer size.

I will need to rewrite net_probe to use tcpdump instead of python-pcap bindings
