Hi,
This set continues with the minor cleanups in the first 6 patches and
patch 7 adds the first new feature - MFC manipulation via netlink.

Hi Nikolay

Great to see somebody working on multicast.

Do you have any plans to remove the 32 VIF limit?

I've run out if VIFs on a VPN server with lots of clients. I took the
"quick fix" of recompiling the kernel and userspace with 256 VIFs. But
it would be nice if you could define a netlink API which does not have
this limit and modify the core code to be more dynamic.

Hi Andrew,
I'm glad people are still using it. :-)  To answer your question - yes, I plan
to remove that limit, in fact I have a private version where it's done and this
API is the first step, you can see it uses the generic rtnh which supports
ifindex passing, so it'll be a matter of a few small changes to remove it.
The hardest part is keeping current user-space compatible with everything, but
I have the necessary workarounds for that. In the end it should be much more
usable and to some extent without mrtsock application running as well.

Thanks,
 Nik
