Curious, are you planning querier per-vlan, including use-ifaddr support
as well?  In our in-house hack, which I posted a few years ago, we added
some "dumpster diving" to inet_select_addr(), but it got rather tricky.
So I've been leaning towards having that in userspace instead.

Yes, that is already supported (use-ifaddr needs attention though). In my next
patch-set where I added the initial global vlan mcast options I added control
for per-vlan querier with per-vlan querier elections and so on. The use-ifaddr
needs more work though, that's why I still haven't added that option. I need
to add the per-vlan/port router control option so we'll have mostly everything
ready in a single release.

Wow, OK now we're talking, yeah that would be great to have in place as well!

Future patch-sets which build on this one (in order):
 - iproute2 support for all the new uAPIs

I'm very eager to try out all the new IGMP per-VLAN stuff, do you have
any branch of the iproute2 support available yet for testing?

I don't have it public yet because I need to polish the support, currently
it's very rough, enough for testing purposes for these patch-sets. :)
I plan to work on that after I finish with the per-vlan/port router control.

Alright, I can appreciate that.  Really looking forward to this, I'll be
patiently waiting here in the wings, testing this out.

Fantastic work with this, again! :)

All the best
