+* Use dev arg option ``drv_loopback=1`` to loopback packets at
+ driver level. Any packet received will be reflected back by the
+ driver on same port. e.g. ``fslmc:dpni.1,drv_loopback=1``
+
+* Use dev arg option ``drv_no_prefetch=1`` to disable prefetching
+ of the packet pull command which is issued in the previous cycle.
+ e.g. ``fslmc:dpni.1,drv_no_prefetch=1``
+
+* Use dev arg option ``drv_tx_conf=1`` to enable TX confirmation mode.
+ 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``
