+* **Added Ethernet PMD power management helper API.**
+
+ A new helper API has been added to make using Ethernet PMD power management
+ easier for the user: ``rte_power_ethdev_pmgmt_queue_enable()``. Three power
+ management schemes are supported initially:
+
+ * Power saving based on UMWAIT instruction (x86 only)
+ * Power saving based on ``rte_pause()`` (generic) or TPAUSE instruction (x86 only)
+ * Power saving based on frequency scaling through the ``librte_power`` library
