Thank you for your reply, Konstantin. Both MBUF_FAST_FREE and indirect mbufs are for performance reasons, but they cannot be used at the same time, which is indeed a pity. In a real-world application, I don't know which method is more conducive to the optimization of overall performance, so I want to add a choice for the application, do you think it is necessary（like rte_ipv4_fragment_clone_packet）?
