That is the goal, but more work needs to be done of course. It won't be possible with just a single pseudo skb, the driver will need a fast way to get batches of pseudo skbs (per core?) through from rx to tx. In mlx4 for instance, either the skb needs to be much more complete to be handled from the start of mlx4_en_xmit(), or that function would need to be split so that the fast tx could start midway through.
Or, skb allocation just gets much faster. Then it should be pretty straightforward. > > Tom
