Russell, Giuseppe,

Have you looked any further at OVN/MidoNet implementations of the SFC API?

It's been a long road to get the initial OvS implementation done and 
there are still some pieces that haven't been merged yet but we'd be 
very interested in feedback on the pluggable driver model.

The intent has always been to create a common SFC API with an 
ML2-inspired separation of the API from the backend so that service 
chains can be created using the same API calls across multiple SDN 
controller backends.

I'd like to capture feedback on the driver model and whether we've got 
the right bits in place to allow for hooking in various SDN controllers.
