Description of problem:
We are seeing in CI that geneve tunnels are constantly getting deleted in OVS, then ovn-controller recreates them and flows fail to get updated:

Comment 1 Aniket Bhat 2020-09-09 16:44:30 UTC

This needs to be pulled down to openshift repo from downstream. Waiting on the next rebase.

Rebase happened in https://github.com/openshift/ovn-kubernetes/pull/269
