Tue 15 Jan 2013 06:39:16 PM UTC, comment #2: Regarding the multicast filters, I guess I'm with Ivan. Unfortunately, I'm not too familiar with IPv6, yet, but I'd rather solve this with good documentation (and an example driver making everything right, probably - is there any?) than calling a filter-add-function right after adding the netif.

Corresponding source code
I see two things that need to be done:
- MLD6 filter callback for netif. Put in skeleton a call to add ff02::1 by default
- Add a function/macro for adding an IPv6 address to a netif. This should handle subscribing to the solicited-node address. Now it is done in ND6 code when an address is set to TENTATIVE, but for other initial stated (e.g. PREFERRED) it is not done.
