(enqueue/dequeue start; enqueue/dequeue finish). That allows user to inspect
objects in the ring without removing them from it (aka MT safe peek).
+* **Added flow aging support.**
+
+ Added flow aging support to detect and report aged-out flows, including:
+
+ * Added new action: ``RTE_FLOW_ACTION_TYPE_AGE`` to set the timeout
+ and the application flow context for each flow.
+ * Added new event: ``RTE_ETH_EVENT_FLOW_AGED`` for the driver to report
+ that there are new aged-out flows.
+ * Added new query: ``rte_flow_get_aged_flows`` to get the aged-out flows
+ contexts from the port.
+
* **Updated Amazon ena driver.**
Updated ena PMD with new features and improvements, including:
Update the Intel iavf driver with new features and improvements, including:
* Added generic filter support.
+ * Added advanced iavf with FDIR capability.
+ * Added advanced RSS configuration for VFs.
* **Updated the Intel ice driver.**
* Added support for matching on IPv4 Time To Live and IPv6 Hop Limit.
* Added support for creating Relaxed Ordering Memory Regions.
+ * Added support for jumbo frame size (9K MTU) in Multi-Packet RQ mode.
+ * Optimized the memory consumption of flow.
* **Updated the AESNI MB crypto PMD.**
Added the new ``igc`` net driver for Intel Foxville I225 devices. See the
:doc:`../nics/igc` NIC guide for more details on this new driver.
+* **Updated Broadcom bnxt driver.**
+
+ Updated Broadcom bnxt driver with new features and improvements, including:
+
+ * Added support for host based flow table management
+ * Added flow counters to extended stats
+ * Added PCI function stats to extended stats
+
* **Added handling of mixed crypto algorithms in QAT PMD for GEN2.**
Enabled handling of mixed algorithms in encrypted digest hash-cipher
* Added IPsec inbound load-distribution support for ipsec-secgw application
using NIC load distribution feature(Flow Director).
+* **Added rte_graph library.**
+
+ Graph architecture abstracts the data processing functions as a ``node`` and
+ ``links`` them together to create a complex ``graph`` to enable reusable/modular
+ data processing functions. The graph library provides API to enable graph
+ framework operations such as create, lookup, dump and destroy on graph and node
+ operations such as clone, edge update, and edge shrink, etc.
+ The API also allows to create the stats cluster to monitor per graph and per node stats.
+
+* **Added rte_node library which consists of a set of packet processing nodes.**
+
+ The rte_node library that consists of nodes used by rte_graph library. Each
+ node performs a specific packet processing function based on application
+ configuration. The following nodes are added:
+
+ * Null node: Skeleton node that defines the general structure of a node.
+ * Ethernet device node: Consists of ethernet Rx/Tx nodes as well as ethernet
+ control APIs.
+ * IPv4 lookup node: Consists of ipv4 extract and lpm lookup node. Routes can
+ be configured by the application through ``rte_node_ip4_route_add`` function.
+ * IPv4 rewrite node: Consists of ipv4 and ethernet header rewrite functionality
+ that can be configured through ``rte_node_ip4_rewrite_add`` function.
+ * Packet drop node: Frees the packets received to their respective mempool.
+
+* **Added new l3fwd-graph sample application.**
+
+ Added an example application ``l3fwd-graph``. It demonstrates the usage of graph
+ library and node library for packet processing. In addition to the library usage
+ demonstration, this application can use for performance comparison with existing
+ ``l3fwd`` (The static code without any nodes) with the modular ``l3fwd-graph``
+ approach.

Removed Items

Also, make sure to start the actual text at the margin.
=========================================================
+* mempool: The API of ``rte_mempool_populate_iova()`` and
+ ``rte_mempool_populate_virt()`` changed to return 0 instead of -EINVAL
+ when there is not enough room to store one object.
