Hi, dpdk-testpmd with AF_XDP PMD can't work on p1p1 (macvlan) interface, but can work on eth0 (veth) interface.
And is there a method to enable AF_XDP PMD to work in XDP SKB mode? Or add one option to set "SKB mode" in AF_XDP Options<https://doc.dpdk.org/guides/nics/af_xdp.html> ? ===============can't work on p1p1 (macvlan) interface==================== 5p8j4:/tmp # ./dpdk-testpmd --log-level=pmd.net.af_xdp:debug --no-huge --no-pci --no-telemetry --vdev net_af_xdp,iface=p1p1 -- --total-num-mbufs 8192 EAL: Detected CPU lcores: 40 EAL: Detected NUMA nodes: 1 EAL: Static memory layout is selected, amount of reserved memory can be adjusted with -m or --socket-mem EAL: Detected static linkage of DPDK EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: VFIO support initialized rte_pmd_af_xdp_probe(): Initializing pmd_af_xdp for net_af_xdp init_internals(): Zero copy between umem and mbuf enabled. testpmd: create a new mbuf pool <mb_pool_0>: n=8192, size=2176, socket=0 testpmd: preferred mempool ops selected: ring_mp_mc Warning! port-topology=paired and odd forward ports number, the last port will pair with itself.
