=======================================================
+* **Added new packet type for UDP-ESP packets in mbuf.**
+
+ Added new packet type ``RTE_PTYPE_TUNNEL_ESP_IN_UDP`` which can be
+ used to identify UDP encapsulated ESP packets.
+
* **Enhanced ethdev representor syntax.**
* Introduced representor type of VF, SF and PF.
