OpenStack Train OVS 2.12
Linux 5.3 from hwe edge
Connect-X 5 running latest firmware from Mellanox.
Overlay networking configured with VXLAN for project networking.
Some instances successfully DHCP, some don't.
For those that don't:
compute:

The response is send from the gateway unit to the compute unit, but is never seen in the tcpdump.
If hardware encap is disabled on the two underlying ports/the card, traffic flow is seen and all instances correctly DHCP configure on boot.
