In this mode tx conf queues need to be polled to free the buffers.
e.g. ``fslmc:dpni.1,drv_tx_conf=1``
+* Use dev arg option ``drv_error_queue=1`` to enable Packets in Error queue.
+ DPAA2 hardware drops the error packet in hardware. This option enables the
+ hardware to not drop the error packet and let the driver dump the error
+ packets, so that user can check what is wrong with those packets.
+ e.g. ``fslmc:dpni.1,drv_error_queue=1``
