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? :-(
