title: Cannot use IOVA as PA in running pipeline application using DPDK
body: <p>I am using DPDK 19.11 in Linux Ubuntu 18 vm. I am able to run PDUMP and testpmd sample applications successfully.</p>
  <p>To execute IP pipeline application, I assigned four ports to DPDK and loaded KNI interface as well. I have used sample firewall.cli configuration from DPDK examples folder. I updated ports address in firewall.cli</p>
  <p>When I start the pipeline application, the following error gets displayed.<br />
  EAL:FATAL Cannot use IOVA as PA since  physical addresses are not available.</p>
  <p>EAL initialization failed.</p>
  <p>Can you please help how to overcome this error and share some more firewall.cli examples.</p>
