 Even though we will work on making this tool as smart as possible, there
 always be cases when manual investigation is required.

 Traffic should be dumped in pcap (tcpdump) format.

 Ideally, it would use some existing library to write traffic in proper
 format.

 Due to time constraints, I don't think we will be able to do this in the
 November 2011 milestone. We could consider temporary solution that could
 work, though:

 Before test: fork() + system("tcpdump -i eth0 dhcp")

 Run tests as usual

 After test: kill tcpdump
