+- ``Lock NPA contexts in NDC``
+
+ Lock NPA aura and pool contexts in NDC cache.
+ The device args take hexadecimal bitmask where each bit represent the
+ corresponding aura/pool id.
+
+ For example::
+
+ -a 0002:02:00.0,npa_lock_mask=0xf

+Traffic Management API
+----------------------
+
+OCTEON TX2 PMD supports generic DPDK Traffic Management API which allows to
+configure the following features:
+
+#. Hierarchical scheduling
+#. Single rate - Two color, Two rate - Three color shaping
+
+Both DWRR and Static Priority(SP) hierarchial scheduling is supported.
+
+Every parent can have atmost 10 SP Children and unlimited DWRR children.
+
+Both PF & VF supports traffic management API with PF supporting 6 levels
+and VF supporting 5 levels of topology.
+
+Limitations
+-----------
+
+``mempool_octeontx2`` external mempool handler dependency
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The OCTEON TX2 SoC family NIC has inbuilt HW assisted external mempool manager.
+``net_octeontx2`` pmd only works with ``mempool_octeontx2`` mempool handler
+as it is performance wise most effective way for packet allocation and Tx buffer
+recycling on OCTEON TX2 SoC platform.
+
+CRC stripping
+~~~~~~~~~~~~~
+
+The OCTEON TX2 SoC family NICs strip the CRC for every packet being received by
+the host interface irrespective of the offload configuration.
+
+Multicast MAC filtering
+~~~~~~~~~~~~~~~~~~~~~~~
+
+``net_octeontx2`` pmd supports multicast mac filtering feature only on physical
+function devices.
+
+SDP interface support
+~~~~~~~~~~~~~~~~~~~~~
+OCTEON TX2 SDP interface support is limited to PF device, No VF support.
+
+Inline Protocol Processing
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+``net_octeontx2`` pmd doesn't support the following features for packets to be
+inline protocol processed.

+- VLAN/QinQ offload
