      This ticket is tracking the QE verification effort for the solution to the problem described below.
      PDK RX perforamnce is dropped when there is a vhu port with no traffic(PMD usage 0%) exists on the same sibling's CPU.

      The issue is observed when DPDK port uses PF and VF.

      Version
      openvswitch3.1-3.1.0-73.el9fdp.x86_64

      How reproducible?
      Always.

      Reproducing step
      1. Deploy RHOSP17.1.2.
      2. On a compute node, launch a VM whose port uses the same sibling's cpus of DPDK port
      3. Shutdown the VM and confirm that the port exists on the same sibling's cpus of DPDK port.
