Create tun/tap device that just copies all packets to/from the given ethernet interface.
Primary use case: workaround non-working "ip link set wlan0 netns ..." for some network drivers.
Secondary use case: simple demo for getting/setting the MAC address, tun/tap, raw sockets...
Pre-built version: http://vi-server.org/pub/tap_copy
