Thanks. I think this is very similar to the patch that u-bmc has, but this
one is an actual nice-looking patch :-). The u-bmc one is just a bunch of
#if 0's around multicast filtering.

What I'm worried about is that we forget why IPv6 works by disabling
multicast filtering, I don't see any elaborate mention of this in the code.
The long-term fix is to make sure the GMF is programmed with the correct
multicast groups to make IPv6 happy, and we shouldn't lose track of that I
feel. However, as an intermediate fix I welcome this patch whole-heartedly.

I will see if I can dig up an eval board to try it on and add a Tested-By
in that case.
