+ Flow metadata has been extended to both Rx and Tx.
+
+ * Tx metadata can also be set by SET_META action of rte_flow.
+ * Rx metadata is delivered to the host via a dynamic field of ``rte_mbuf``
+ with ``PKT_RX_DYNF_METADATA``.
+
+* **Added ethdev API to set supported packet types.**
+
+ * Added new API ``rte_eth_dev_set_ptypes`` which allows an application to
+ inform a PMD about a reduced range of packet types to handle.
+ * This scheme will allow PMDs to avoid lookup of internal ptype table on Rx
+ and thereby improve Rx performance if the application wishes to do so.
+
+* **Added Rx offload flag to enable or disable RSS update.**
+
+ * Added new Rx offload flag ``DEV_RX_OFFLOAD_RSS_HASH`` which can be used to
+ enable/disable PMDs write to ``rte_mbuf::hash::rss``.
+ * PMDs notify the validity of ``rte_mbuf::hash:rss`` to the application
+ by enabling ``PKT_RX_RSS_HASH`` flag in ``rte_mbuf::ol_flags``.
+
+* **Added Rx/Tx packet burst mode "get" API.**
+
+ Added two new functions ``rte_eth_rx_burst_mode_get`` and
+ ``rte_eth_tx_burst_mode_get`` that allow an application
+ to retrieve the mode information about Rx/Tx packet burst
+ such as Scalar or Vector, and Vector technology like AVX2.
