-  Added packet mode in the meter profile parameters data structures
-  to support metering traffic by packet per second (PPS),

+* **Added Predictable RSS functionality to the Toeplitz hash library.**
+
+  Added feature for finding collisions of the Toeplitz hash function -
+  the hash function used in NICs to spread the traffic among the queues.
+  It can be used to get predictable mapping of the flows.

 * **Updated testpmd.**
 
   * Added a command line option to configure forced speed for Ethernet port.
     ``dpdk-testpmd -- --eth-link-speed N``
   * Added command to display Rx queue used descriptor count.
     ``show port (port_id) rxq (queue_id) desc used count``
