Please consider comparing your model with what is described here [0].
I'm trying to write down an architecture document that we can finalize
in Düsseldorf.

I think you are saying that the kernel should not be required to make
the offload decision which is fair. We definitely don't want to force
the decision to be outside though, there are several legit reasons to
support transparent offloads within the kernel as well outside of OVS.
