Agreed. I think John was pointing out how this is achievable with the
flow API while integrating into existing kernel concepts.
The point I was making is that if you have iptables ACLs that you want
offloaded you need all dependencies leading up to that iptables rule to
be programmed into hardware as well. A VRF implemented as netns is a
typical example for this but any form of network virtualization will
require this.
