This means ``ethtool "-a|--show-pause", "-s|--change"`` won't work, and
``ethtool <iface>`` output will have less information.
+* KNI, by default interface carrier status is ``off`` which means there won't be any traffic.
+ It can be set to ``on`` via ``rte_kni_update_link()`` API or via ``sysfs`` interface:
+ ``echo 1 > /sys/class/net/vEth0/carrier``. Note interface should be ``up`` to be able
+ to read/write sysfs interface.
+ When KNI sample application is used ``-m`` parameter can be used to automatically update
+ the carrier status for the interface.
