Only the destination network is matched for deciding on NAT64, as
priority based double LPM is not supported. This limits a prefix to be
used only in one network.
**** TODO No resolution of hardware addresses
- hardcoded ip --> mac addresses
Correct version:
Resolve mac address in controller, buffer packet, replay packet /
handle packet.
Only has to be set, when packets originate from the switch/controller.
