Build Update for dceara/ovn
-------------------------------------

Build: #27
Status: Passed

Duration: 44 mins and 39 secs
Commit: 266b3d2 (multicast-router-v3)
Author: Dumitru Ceara
Message: ovn-northd: Add IGMP Relay support

Add a new configuration option 'mcast_relay' to the Logical_Router:options
in the OVN Northbound database.

If a router is configured with 'mcast_relay' enabled then ovn-northd
will install Logical_Flows to allow IP multicast traffic to be routed
between Logical_Switches. The logical router will aggregate all IGMP
groups from attached logical switches and modify the routing pipeline in
the following way:
- Table S_ROUTER_IN_IP_INPUT: add flow allowing IP multicast traffic
  if mcast_relay is enabled on the datapath.
- Table S_ROUTER_IN_IP_ROUTING: add flow matching the group address,
  update TTL and set outport="<Multicast_Group> associated with the
  IGMP group". Continue to next table.
- Table S_ROUTER_IN_ARP_RESOLVE: bypass ARP resolve for IP multicast
  traffic and continue to next table.
- Table S_ROUTER_OUT_DELIVERY: add flow matching IP multicast traffic
  and set ETH.SRC to the MAC address of the logical port on which
  traffic is forwarded.
