Hi All,

     I am planning to use dpdk r= eorder library in my application.

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 alr= eady or use the existing buffer.

3.iterate through the rx packets and set the sequenc= e number using *rte_reorder_seqn(pkt) =3D seqn++.

4.insert the packets using the API rte_reorder_inser= t(ro_buf, pkt);

5.after insert completed I am using rte_reorder_drai= n API to get the reorder packets .

 

In step 5 always getting zero packets.

Even though all the rx packets are in order rte_reod= er_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 port= s .

Sent traffic in port 1 there is no packet out in por= t 1 as mentioned in application example page.

https://doc.dpdk.org/guides/sample_app_ug/packet_ordering.html<= o:p>

Bala
