Hi, Could you take a look at the app/test/test_reorder.c `test_reorder_drain()` test case. It follows your steps closely and includes comments that describe the internal state of buffers, which could be helpful during debugging.

Used reorder library API's by refereeing the packet ordering example. Steps: Our application uses dpdk pipeline. 1.read the packet from rx 2.Create the rte_reorder_create() if not created already or use the existing buffer. 3.iterate through the rx packets and set the sequence number using *rte_reorder_seqn(pkt) = seqn++. 4.insert the packets using the API rte_reorder_insert(ro_buf, pkt); 5.after insert completed I am using rte_reorder_drain API to get the reorder packets . In step 5 always getting zero packets. Even though all the rx packets are in order rte_reoder_drain API not giving the output. Could any please help on this am I missing anything in the implementation . How to use this library properly. Tried to run the packet ordering example with 4 ports . Sent traffic in port 1 there is no packet out in port 1 as mentioned in application example page. https://doc.dpdk.org/guides/sample_app_ug/packet_ordering.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__doc.dpdk.org_guides_sample-5Fapp-5Fug_packet-5Fordering.html&d=DwMFAg&c=nKjWec2b6R0mOyPaz7xtfQ&r=4iVvgx5PfauIDNaDpT1Ph7naVrkBkhwh2wdQ1AUXVjo&m=LRnVWVWJFPG262ii-XDMQhsmNnSxIXzBIwBY_fRUQsmMdsEDvqC9-T16uF0eYOxo&s=1Oji8GpXbRO608Vsx4e_m1MT1oOXqYA1hx5C6JSiDLY&e=> Regards, Bala
