[ovs-dev] [PATCH 0/4] OVN: Add IGMP support

[Dumitru Ceara]

This series introduces support for IGMP Snooping and IGMP Querier. IGMP
versions v1-v3 are supported for snooping and IGMP queries originated by
ovn-controller are general IGMPv3 queries. The rationale behind using v3 for
querier is that it's backward compatible with v1-v2.

The majority of the code is IP version independent with the thought in mind
that support for MLD snooping for IPv6 will be added next.

Dumitru Ceara (4):
      packets: Add IGMPv3 query packet definitions
      OVN: Add IGMP SB definitions and ovn-controller support
      OVN: Add ovn-northd IGMP support
      OVN: Add IGMP tests
