Now all XDP driver have been updated to setup xdp_rxq_info and assign this to xdp_buff->rxq. Thus, it is now safe to enable access to some of the xdp_rxq_info struct members. This patch extend xdp_md and expose UAPI to userspace for ingress_ifindex and rx_queue_index. Access happens via bpf instruction rewrite, that load data directly from struct xdp_rxq_info. * ingress_ifindex map to xdp_rxq_info->dev->ifindex * rx_queue_index map to xdp_rxq_info->queue_index Signed-off-by: NJesper Dangaard Brouer <brouer@redhat.com> Acked-by: NAlexei Starovoitov <ast@kernel.org> Acked-by: NJohn Fastabend <john.fastabend@gmail.com> Signed-off-by: NAlexei Starovoitov <ast@kernel.org>
