When compared to v1 (which can be found under ), two new patches are introduced that are focused on improving the performance for XDP_TX as Jussi reported that the numbers were pretty low on his side. Furthermore the fallback path is now based on static branch, as suggested by Toke on v1. This means that there's no further need for a standalone net_device_ops that were serving the locked version of ndo_xdp_xmit callback. Idea from 2nd patch is borrowed from a joint work that was done against OOT driver among with Sridhar Samudrala, Jesse Brandeburg and Piotr Raczynski, where we working on fixing the scaling issues for Tx AF_XDP ZC path. Last but not least, with this series I observe the improvement of performance by around 30%. Thanks!
