IP/UDP packet reordering

[sysman at scaled.cloud]

Hello there!

  I have tried to get experience with the DPDK, so, I wrote a small app 
based on the L2FWD.
  Simple schema: VM/DPDK -----10Gb DAC ---- VM/DPDK. When I performs a 
testing of traffic pass with the IPERF3 I getting:

...
[SUM]  0.0-10.0 sec  40844 datagrams received out-of-order
...

So, what I'm need to check additionally to understand how control of 
order is performed in the DPDK/EAL engine ?

TIA.
