I am not sure what to do in order to deal with such an interoperability issue. The IPv6 layer has no way of knowing what the capabilities are of the other NICs on a LAN.
Do you have a proposal to address such issues?

Yep but about the transmitter that _does_ have the multicast capability and the receiver that does not have the multicast capability.
On the receive side, these cards would go into promiscuous receive mode and then filter at the device driver.
Yes but what about cards that can't go into promiscuous receive mode. I understand that promiscuous mode is probably the easiest way for a card to do, but from my experience not all cards can do promiscuous mode.
