[ovs-dev] [PATCH v4 ovn 0/3] Introduce check_pkt_larger for ingress traffic

[Lorenzo Bianconi]

In the current codebase, check_pkt_larger is applied just for traffic
leaving the ovn cluster. This series introduces the same capability
for traffic entering the network from a gateway router or distributed
gateway router port in order to send an ICMP error packet if the frame
size is greater than the configured MTU.

Changes since v3:
- add missing documentation
- add DDlog implementation

Changes since v2:
- squash gw router and distributed gw router tests
- fix typos

Changes since v1:
- drop router pipeline rearrangement
- refer to check_pkt_larger instead of check_pkt_len

Lorenzo Bianconi (3):
  northd: introduce build_check_pkt_len_flows_for_lrp routine
  northd: enable check_pkt_larger for gw router
  northd: add check_pkt_larger lflows for ingress traffic
