No, I'm not aware of the issue.

The issue can happen on a NIC with incorrectly programmed ethernet
address. Would you show me dmesg/tcpdump output of your system?
Make sure to add -e option to tcpdump(1).

It's more likely a problem with the multicast filter programming.
IPv6 is all about the multicasting (neighbord discovery depends on it
to work correctly). I can't explain why it's not working though.
I've tested the sample 8168B/8111B cards that RealTek sent me, and I
didn't have any multicast problems with them.
