that's a great idea. To simulate something like this it's possible to attach cls_bpf to veth or tap device and tcpreplay pcap into it. For xdp that would need some kernel work, since spinning a VM with virtio and sending pcap into tap is too cumbersome. _______________________________________________ iovisor-dev mailing list iovisor-dev@lists.iovisor.org https://lists.iovisor.org/mailman/listinfo/iovisor-dev
