Based on the scenarios in the README, add a small selftest suite. It should be executed with root privileges. Additionally, add a separate scenario testing the pcap filter expression matches in-depth. This excercise L3 and L4 matches with synthetic test packets (AF_PACKET raw data injection, not ping/tcpdump).
