The RSS hash report is a feature that's part of the virtio specification. Currently, virtio backends like qemu and vdpa (mlx5) support it(potentially vhost). While the capability to obtain the RSS hash has been enabled in the normal path, it's currently missing in the XDP path. Changes from v1: - introduce a wrapper structure to preserve virtio header Liang Chen (3): virtio_net: Preserve virtio header before XDP program execution virtio_net: Add missing virtio header in skb for XDP_PASS virtio_net: Support RX hash XDP hint drivers/net/virtio_net.c | 102 ++++++++++++++++++++++++++++++++++----- 1 file changed, 90 insertions(+), 12 deletions(-) -- 2.40.1
