+* **Updated KNI kernel module, rte_kni library, and KNI sample application.**
+
+ Updated the KNI kernel module with a new kernel module parameter,
+ ``carrier=[on|off]`` to allow the user to control the default carrier
+ state of KNI kernel network interfaces. The default carrier state
+ is now set to ``off``, so the interfaces cannot be used until the
+ carrier state is set to ``on`` via ``rte_kni_update_link`` or
+ by writing ``1`` to ``/sys/devices/virtual/net/<iface>/carrier``.
+ In previous versions the default carrier state was left undefined.
+ See :doc:`../prog_guide/kernel_nic_interface` for more information.
+
+ Added the new API function ``rte_kni_update_link`` to allow the user
+ to set the carrier state of the KNI kernel network interface.
+
+ Added a new command line flag ``-m`` to the KNI sample application to
+ monitor and automatically reflect the physical NIC carrier state to the
+ KNI kernel network interface with the new ``rte_kni_update_link`` API.
+ See :doc:`../sample_app_ug/kernel_nic_interface` for more information.
