Tapping 802.1x Links with Marvin

While testing fat clients and appliances for resistance against man-in-the-middle attack I always had to mess with iptables/ebtables/socat to divert network connections. It is enough in most cases, but sometimes the setup gets too elaborate. To make my life easier, I have decided to write a tool, capable to divert and re-inject a network connections while preserving the original network addresses, including layer 2 ones. The tool is not complete yet, but it already can be used to tap into a wired network protected with 802.1x, so I've decided to publish it anyway.
