As I've said earlier I'm working and cleaning up of the stack/driver
interface and API.  It started out to better integrate the offload
capabilities, reduce code duplication and to audit their usage in the
drivers.  While doing that I've noticed, as others have, a couple more
issues including the queuing problem.  So work is under way and by
early next year a prototype for further discussion should be ready.
