Erm... noone ?

I would like to learn more about OVN and especially the maximum MTU that I can use in my
Current Setup 4.3.10
Network was created via UI -> MTU Custom -> 8976 -> Create on External Provider
-> Connect to Physical Network
So my physical connection is MTU 9000 and I have read that Geneve uses 24 bits (maybe
that's wrong ?) , thus I have reduced the MTU to 8976.
I did some testing on the VMs and ping with payload of '8914' was the maximum I
could pass without fragmenting and thus the MTU on the VMs was set to 8942.
Did I correctly configure the test network's MTU and am I understanding it correctly
that we need extra 34 bits inside the network for encapsulation ?
but I don't see any refference how to calculate the max MTU.
