Fix the behavior of the 'ip link set dev $ETHX vf $VF_NUM state disable' to completely shutdown the VF's queues making it entirely disabled and not able to receive or send any traffic. Modify the behavior of the 'ip link set $ETHX vf $VF_NUM state enable' command to make a VF do reinitialization bringing the queues back up.
