Numan and I have discussed this, and we're planning to perform the split 
tomorrow July 25. Numan will be applying the commits he referenced below 
to the ovn-org branch to get it up to date. I will be submitting a 
review for OVS to remove all of the OVN code, documentation, etc. from it.

If there are any reasons why we should hold off on this, please mention 
them as soon as possible.
