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
