Hey! I think that video was showing some out of tree patches and hacks. At the time there was hope that bpfilter will become a commonly used iptables to BPF translation layer, but unfortunately the effort haven't gone far beyond laying the groundwork. Maybe you are the person who will take it forward? :) FWIW there are also projects for doing such translation in user space, there are patches for OvS to generate XDP programs, libkefir from Netronome, and I think Red Hat was also working on something?
