Same tree, kernel-tables-wip-02 branch. Compile kernel and install. Compile samples as before. If you give the userspace program a -t arg, it loop showing stats. Ctrl-C to break. The xdp programs are not detached on exit. Example: ./xdp_fwd -t 5 eth1 eth2 eth3 eth4 15:59:32: rx tx dropped skipped l3_dev fib_dev index 3: 901158 901158 0 18 0 0 index 4: 901159 901158 0 20 0 901139 index 10: 0 0 0 0 19 19 index 11: 0 0 0 0 901139 901139 index 15: 0 0 0 0 19 19 index 16: 0 0 0 0 901139 0 Rx and Tx counters are for the physical port. VLANs show up as l3_dev (ingress) and fib_dev (egress). dropped is anytime the xdp program returns XDP_DROP (e.g., invalid packet) skipped is anytime the program returns XDP_PASS (e.g., not ipv4 or ipv6, local traffic, or needs full stack assist).
