I was experiencing issues with OpenStack deployed with Networking OVN and just saw this message in my dmesg:

---
[ 12.241706] 8021q: adding VLAN 0 to HW filter on device eno2
[ 15.077293] eno2: Invalid MTU 9000 requested, hw max 68
---

And the IP of my eno2.600 VLAN is gone! So, the Instances can't ping each other because that is where my data path (GENEVE / VXLAN) tunnels are created on!

How a bug like this ended up into an LTS release? :-(
