Awesome work, this looks very interesting! :)  I've already built and
tested net-next for regressions on Marvell SOHO switches, looking good
so far.

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.

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?  For now
I've hard-coded BROPT_MCAST_VLAN_SNOOPING_ENABLED in br_multicast_init()
as a workaround, and everything seems to work just as expected :-)

Best regards
