With respect to the previous implementation, OVN is now tracking and
flushing ECMP next-hop ct entries with the next-hop mac address instead
of using an identification number committed by ovn-northd since the previous
approach had some limitations when the traffic is initialized from outside
the ovn cluster. This series is introducing a way to periodically resolve L2
address of the configured next-hops.
Please note IPv6 is not currently supported and it will be added before posting
a formal series. The goal of this series is just to collect feedbacks about the
proposed approach.

Changes in v2:
- add IPv6 support

Lorenzo Bianconi (4):
  northd: Introduce ECMP_Nexthop table in SB db.
  pinctrl: Send periodic arp/nd to ecmp next-hops.
  pinctrl: Update ecmp-nexthop mac resolving L2 address.
  ofctrl: Introduce ecmp_nexthop_monitor.
