When using net/af_xdp DPDK driver along OVS native AF_XDP support, confusing logs are reported, like: netdev_dpdk|INFO|Device 'net_af_xdpp0,iface=ovs-p0' attached to DPDK dpif_netdev|INFO|PMD thread on numa_id: 0, core id: 11 created. dpif_netdev|INFO|There are 1 pmd threads on numa node 0 dpdk|INFO|Device with port_id=0 already stopped dpdk(pmd-c11/id:22)|INFO|PMD thread uses DPDK lcore 1. netdev_dpdk|WARN|Rx checksum offload is not supported on port 0 netdev_afxdp|INFO|libbpf: elf: skipping unrecognized data section(6) .xdp_run_config netdev_afxdp|INFO|libbpf: elf: skipping unrecognized data section(7) xdp_metadata netdev_afxdp|INFO|libbpf: elf: skipping unrecognized data section(7) xdp_metadata netdev_afxdp|INFO|libbpf: elf: skipping unrecognized data section(7) xdp_metadata This comes from the fact that netdev-afxdp unconditionnally registers a helper for logging libbpf messages. Making both net/af_xdp and netdev-afxdp work at the same time seems difficult, so at least, ensure that netdev-afxdp won't register this helper unless a netdev is actually allocated.
