<li>I see the same result while using dpdk-testpmd on the APP side.</li></ol>

<li>As per this page, <a href="https://doc.dpdk.org/guides/tools/pdump.html"><font color="#467886"><u>https://doc.dpdk.org/guides/tools/pdump.html</u></font></a>.</li></ol>
<div style="padding-left:36pt;">Is this applicable to vmxnet3 device here ??</div>
<div style="padding-left:36pt;"> </div>
<ul style="margin:0;padding-left:54pt;">
<li><span style="background-color:yellow;"><i>As of now the dpdk-pdump tool cannot capture the packets of virtual devices in the primary process due to a bug in the ethdev library. Due to this bug, in a multi process context, when the primary and secondary
have different ports set, then the secondary process (here the dpdk-pdump tool) overwrites the rte_eth_devices[] entries of the primary process.</i></span></li></ul>
