Petr Lampa - who opened the PR - explained me provately about the embedded scope. However I still think this collides with RFC3306 addresses. The other point discussed with Petr Lampa is about the ff02::2:xxxx:xxxx addresses. However the addresses are different than defined in RFC4620, where they have the format ff02::2:ffxx:xxxx. -- B.Walter <bernd@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm.
