Thanks Lorenzo for this series and Mark G for the reviews.
I applied the series to the main branch.
Can you please submit a follow up patch adding a NEWS entry for this ?
I also did the below changes to the 3rd patch as the below test cases
were failing
877: ovn -- gateway mtu check pkt larger flows -- ovn-northd-ddlog --
dp-groups=yes FAILED (ovn-northd.at:4819)
878: ovn -- gateway mtu check pkt larger flows -- ovn-northd-ddlog --
dp-groups=no FAILED (ovn-northd.at:4819)
It was just an issue in ordering of actions between ovn-northd-c and
ovn-northd-ddlog.
