<p class="MsoNormal">Hi All,<u></u><u></u></p>
<p class="MsoNormal"> We have intel 810-C 100 Gig NIC and have ESXI v7.0 OS with Ubuntu 20.04.5 VMs.
<u></u><u></u></p>
<p class="MsoNormal">We have SRIOV – VFs into the VM that are seen on latest iavf drivers. And we did bind of VF with igb_uio driver.<u></u><u></u></p>
<p class="MsoNormal">We used <b>dpdk-testpmd</b> from <b>dpdk-22.07</b> to send packets with VLAN and without VLAN tagging.<u></u><u></u></p>
<p class="MsoNormal">When we use VLAN tagging packets are not transmitted instead
<b>Tx errors are seen</b>. Without VLAN tagging packets are sent without any errors.<u></u><u></u></p>
<p class="MsoNormal">More details on setup : <u></u><u></u></p>
