IPv6

• The Linux kernel doesn't forward link local groups (RFC 4291). So multicast groups should look like ff05:XX or ff15:XX.
• The mcproxy doesn't support MLDv2 at the moment. If a multicast listener subscibe a group (normally with a MLDv2 Report) then the mcproxy cannot process this report. So the mcproxy doesn't notice the listener until the mcproxy send a MLDv1 Query and the listener has to answer with an MLDv1 Report. If the MLD version of the listener set to MLDv1 then this delay can be avoid. This can be done with the following command:

 echo 1 > /proc/sys/net/ipv6/conf/<inerface>/force_mld_version

The upstream of the mcproxy has the same problem.
