We had almost the same problem at Nicira when we were separately
developing OVS and our controller NVP. We sort-of solved it as the OVS
team by trying to stay a couple of releases ahead of NVP. It mostly
worked because the OVS team was more nimble than the NVP team and we
were usually able to point out why they didn't really need a new feature
from us anyway.
