However, I believe configuring forwarding is user's responsibility
and I'm not in favor of managing mc_forwarding automatically.

If we go your way, we need to make the proc interface read-only, but
you know, they will become non-"conf" interface. :-(
And, well, we will introduce another possible overflow/underflow here...

Another thought was to allow non-VIF routing settings (or manual settings).

So, I decided to drop that bits.

Thanks for looking it over.

I think your approach to handling mc_forwarding makes sense, although
it differs from the IPv4 behavior.  In any case, it looks like the
current IPv4 and IPv6 multicast routing code does not consider an
interface's mc_forwarding value at all.

Thanks guys.

Hideaki-san, did you queue this patch up or do you want me to
apply it with the mc_forwarding counter bumps removed?

These are bug fixes so I'd like to see this in the tree soon.
