when dedicated queues are enable with bonding mode 4 (mlx5), the application sets the flow, which cannot be set if the device is not started. This fixed the issue by starting the device just before setting the flow. Because device should be started to set the flow. Also it does not effect other driver codes (I have tried on ixgbe).
