  <p>Ports are there, but still i can't run dpdk using  "0000:43:00.0 '82599EB"   </p>
  
  <p>what is the problem ?    </p>
  
  <p>Same configuration i am using to run DPDK for 0000:46:00.0 and 0000:43:00.0. but the above 82599EB NIC is not running why?    </p>
  
  <p><strong>The same time Dpdk is able to run with 0000:46:00.0 'Device 155d' [This LOGS are below]</strong>    </p>
