<p class="MsoNormal"><span lang="EN-US">We have a requirement to create two SR-IOV resource lists from same physical interface. This requirement is for a use case where we are running Intel Flexran software in a Kuberenetes pod. The Intel Flexran software
requires that a u-plane VLAN is assigned to a VF and passed as u-plane VF to the software command line. Similarly, a c-plane VLAN needs to be assigned to a VF and passed as c-plane VF to the software command line. The SR-IOV daemon set supports this configuration:<o:p></o:p></span></p>
