+- ``Maximum queue pairs limit`` (default ``63``)
+
+   The number of maximum queue pairs supported by the device, can be limited
+   during runtime by using ``max_qps_limit`` ``devargs`` parameter.
+
+   For example::
+
+      -a 0002:20:00.1,max_qps_limit=4
+
+   With the above configuration, the number of maximum queue pairs supported
+   by the device is limited to 4.

+Lookaside IPsec Support
+-----------------------
+
+The OCTEON cnxk SoCs can accelerate IPsec traffic in lookaside protocol mode,
+with its **cryptographic accelerator (CPT)**. ``OCTEON cnxk crypto PMD`` implements
+this as an ``RTE_SECURITY_ACTION_TYPE_LOOKASIDE_PROTOCOL`` offload.
+
+Refer to :doc:`../prog_guide/rte_security` for more details on protocol offloads.
+
+This feature can be tested with ipsec-secgw sample application.
