      Description of problem:
      Start a VM with 16+ CPUs - no connectivity if networkInterfaceMultiqueue is enabled

      Version-Release number of selected component (if applicable):
      cluster-network-addons-operator version v4.10.0-41

      How reproducible:

      Steps to Reproduce:
      1. Start a VM with 16 CPUs (tested on a cluster with 3 SR-IOV interfaces)

      Actual results:
      The VM cannot ping the node
      If networkInterfaceMultiqueue is disabled, there's connectivity between the VM and the node

      Expected results:
      The VM should be able to reach the node
