Fix ebtables dhcpv6 rules
the ports were interchanged, see the following packet flow: client:546 --> [ff02::1:2]:547 server:547 --> client:546 therefore we need to allow outgoing multicast packets with dst-port 547 and unicast packets from bat0 to clients with dst-port 546 and 547 in the other direction
