Hi all,
This patch-set implements the control plane for initial IGMPv3/MLDv2
support which takes care of include/exclude sets and state transitions
based on the different report types.
Patch 01 arranges the structure better by moving the frequently used
fields together, patch 02 factors out the port group deletion code which is
used in a few places. Patches 03 and 04 add support for source lists and
group modes per port group which are dumped. Patch 05 adds support for
group-and-source specific queries required for IGMPv3/MLDv2. Then patch 06
adds support for group and group-and-source query retransmissions via a new
rexmit timer. Patches 07 and 08 make use of the already present mdb fill
functions when sending notifications so we can have the full mdb entries'
state filled in (with sources, mode etc). Patch 09 takes care of port group
expiration, it switches the group mode to include and deletes it if there
are no sources with active timers. Patches 10-13 are the core changes which
add support for IGMPv3/MLDv2 reports and handle the source list set
operations as per RFCs 3376 and 3810, all IGMPv3/MLDv2 report types with
their transitions should be supported after these patches. I've used RFCs
3376, 3810 and FRR as a reference implementation. The source lists are
capped at 32 entries, we can remove that limitation at a later point which
would require a better data structure to hold them. IGMPv3 processing is
hidden behind the bridge's multicast_igmp_version option which must be set
to 3 in order to enable it. MLDv2 processing is hidden behind the bridge's
multicast_mld_version which must be set to 2 in order to enable it.
Patch 14 improves other querier processing a bit (more about this below).
And finally patch 15 transforms the src gc so it can be used with all mcast
objects since now we have multiple timers that can be running and we
need to make sure they have all finished before freeing the objects.
This is part 1, it only adds control plane support and doesn't change
the fast path. A following patch-set will take care of that.

Applied thank you.
