+Lookaside IPsec Support
+-----------------------
+
+The OCTEON TX2 SoC can accelerate IPsec traffic in lookaside protocol mode,
+with its **cryptographic accelerator (CPT)**. ``OCTEON TX2 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.
