[ovs-dev] [PATCH ovn 0/2] Improve Load Balancer performance.

[Dumitru Ceara]

This series improves load balancer performance in specific deployments
(e.g., ovn-kubernetes) twofold:

- patch 1/2 changes the way ARP responder flows are generated for load
  balancer VIPs, using an address set, making SB updates incremental
  and also reducing memory usage on the SB server side.
- patch 2/2 introduces a new feature, Load_Balancer_Group, which
  simplifies load balancer configuration in large scale scenarios and
  at the same time improves performance due to the large reduction in
  database refereces between rows.

NOTE: This series doesn't have the corresponding ovn-northd-ddlog
changes.  It wasn't clear to me what direction ovn-northd-ddlog is
going to but if needed, I can implement the ddlog counterpart in v2
or a follow up patch..

Dumitru Ceara (2):
      northd: Use address sets for ARP responder flows for VIPs.
      nb: Add support for Load_Balancer_Groups.
