Thanks for this method. I will update the sample and do some more tests.

I think the first xdpf will be consumed by the driver and the later
xdpf_clone() will failed, won't it?

How about just do a xdp_return_frame_rx_napi(xdpf) after all nxdpf enqueue?

BTW, I forgot to ask, why we don't need the READ_ONCE for ex_map?
I though the map and ex_map are two different pointers.
