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

Build: #24
Status: Passed

Duration: 30 mins and 4 secs
Commit: c64fa06 (multicast-router-v2)
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 matching the group address and
  set outport=<Multicast_Group> associated with the IGMP group. Continue
  to next table.
- Table S_ROUTER_IN_IP_ROUTING: bypass route lookup for IP multicast
  traffic and just decrement TTL. If the packet reached this table then
  it must have matched a flow in S_ROUTER_IN_IP_INPUT and had outport
  set. 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.

v2:
- Optimize flooding to multicast router ports.
- Fix check for source IP multicast in router pipeline.
- Use an enum for OVN_MCAST_*_KEY definitions to avoid hard to debug
  errors due to typos when adding new OVN_MCAST_*_KEY values.
- Fix ovn-northd man page for IGMP.
