Many thanks for your information. I am not a user of that feature but some learner. I am trying to find out all the basic combination used for the virtualization. So I assume that as shown in your slides, the following alternative solutions could be used:
1. Tun/Tap - Recently tap PMD patch sent
2. af_packet
3. virtio-user + vhost-net
4. Bifurcated driver
Am I right? Or is there any new feature?
