(Please don't drop the list.) If you are using the OVS kernel module that ships with a 4.15 kernel, I would expect there to be a problem. (I would also expect there to be a message logged from that probe.) However, if you use the kernel module that ships with OVS (regardless of the kernel it's compiled against), I would expect it to work.
