Do you have any suggestions about how to test it? I'd like to try forwarding pkts to 10+ ports. But I don't know how to test the throughput.

So we need to keep the initial for clone.

Yes, I have tried to combine these two functions together. But one is generic code path and another is XDP code patch. One use skb_clone and another use xdpf_clone(). There are also some extra checks for XDP code. So maybe we'd better just keep it as it is. > > diff --git a/tools/include/uapi/linux/bpf.h b/tools/include/uapi/linux/bpf.h > > index 2e29a671d67e..1dbe42290223 100644 > > --- a/tools/include/uapi/linux/bpf.h > > +++ b/tools/include/uapi/linux/bpf.h > > Updates to tools/include should generally go into a separate patch. Will fix it, thanks. Best Regards Hangbin
