Public bug reported:
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:

IP 172.16.0.2.bootps > 172.16.2.236.bootpc: BOOTP/DHCP, Reply, length 328
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.
