Bug Description

This is proposal to add new config option to OVS agent's section to enable multicast snooping in br-int by neutron-ovs-agent.
This option can be useful for users who wants to have support for multicast traffic which will be treated as "real" multicast instead of broadcast delivered to all ports.

Some details about this are described in https://gist.github.com/djoreilly/a22ca4f38396e8867215fca0ad67fa28

From neutron's point of view it would required only config option in neutron-ovs-agent and some code changes on agent's side.
No any changes in API or DB layers are required by that RFE.

    Add "igmp_snooping_enable" config option for OVS agent

    Neutron-ovs-agent can now enable IGMP snooping in integration bridge
    if config option "igmp_snooping_enable" in OVS section in config will
    be set to True.
    It will also set mcast-snooping-disable-flood-unregistered=true
    so flooding of multicast packets to all unregistered ports will be
    disabled also.
    Both changes are applied on integration bridge.
