That said, it is important to understand that getting raw "fast" frames into your "virtio_net" virtual netcard is a two-stage "rocket". The owner of the hardware box also need a native-XDP netcard that runs XDP which XDP-redirect frames into your virtual NIC, else there is not performance advantage. -- Best regards, Jesper Dangaard Brouer MSc.CS, Principal Kernel Engineer at Red Hat LinkedIn: http://www.linkedin.com/in/brouer
