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

+  * Added new field ``queue_state`` to ``rte_eth_rxq_info`` structure to
+    provide indicated Rx queue state.

   * This also reduced the scheduling overhead on a event device.
 
+* **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``
+  * Added command to cleanup a Tx queue's mbuf on a port.
+    ``port cleanup (port_id) txq (queue_id) (free_cnt)``
   * Added command to dump internal representation information of single flow.
     ``flow dump (port_id) rule (rule_id)``
+  * Added commands to create and delete meter policy.

+* ethdev: The experimental flow API for shared action has been generalized
+  as a flow action handle used in rules through an indirect action.
+  The functions ``rte_flow_shared_action_*`` manipulating the action object
+  are replaced with ``rte_flow_action_handle_*``.
+  The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be
