Merge branch 'XDP-transmission-for-tuntap'
Jason Wang says: ==================== XDP transmission for tuntap This series tries to implement XDP transmission (ndo_xdp_xmit) for tuntap. Pointer ring was used for queuing both XDP buffers and sk_buff, this is done by encoding the type into lowest bit of the pointer and storin XDP metadata in the headroom of XDP buff. Tests gets 3.05 Mpps when doing xdp_redirect_map from ixgbe to VM (testpmd + virtio-net in guest). This gives us ~20% improvments compared to use skb during redirect. Please review. Changes from V1: - slient warnings - fix typos - add skb mode number in the commit log ==================== Signed-off-by: David S. Miller <email@example.com>
