I think we need to add some filtering so we don't process packets
addressed to other nodes, just pass them to the promiscuous mode buffer.
I will have a look next week at a fix.

It is in promiscuous mode as the hardware does not support address
filtering yet...

Just setup any three nodes so they can all see each other and setup a
wireshark sniffer.
Enable ipv6 forwarding by:
echo 1 > /proc/sys/net/ipv6/conf/all/forwarding
I guess you will also have to hack your hardware driver to put your
hardware in promiscuous mode.
Then just do a simple ping from one node to another using link local
addresses.
