memory that was created outside of DPDK's own page allocator, and using that
memory natively with any other DPDK library or data structure.
+* **Added hot-unplug handle mechanism.**
+
+ ``rte_dev_hotplug_handle_enable`` and ``rte_dev_hotplug_handle_disable`` are
+ for enabling or disabling hotplug handle mechanism.
+
+* **Support device multi-process hotplug.**
+
+ Hotplug and hot-unplug for devices will now be supported in multiprocessing
+ scenario. Any ethdev devices created in the primary process will be regarded
+ as shared and will be available for all DPDK processes. Synchronization
+ between processes will be done using DPDK IPC.
+
+* **Added new Flow API actions to rewrite fields in packet headers.**
+
+ Added new Flow API actions to:
+
+ * Modify source and destination IP addresses in the outermost IPv4/IPv6
+ headers.
+ * Modify source and destination port numbers in the outermost TCP/UDP
+ headers.
+
+* **Added new Flow API action to swap MAC addresses in Ethernet header.**
+
+ Added new Flow API action to swap the source and destination MAC
+ addresses in the outermost Ethernet header.
+
* **Add support to offload more flow match and actions for CXGBE PMD**
Flow API support has been enhanced for CXGBE Poll Mode Driver to offload:
* Match items: destination MAC address.
- * Action items: push/pop/rewrite vlan header.
+ * Action items: push/pop/rewrite vlan header,
+ rewrite IP addresses in outermost IPv4/IPv6 header,
+ rewrite port numbers in outermost TCP/UDP header.
* **Added a devarg to use the latest supported vector path in i40e.**
A new devarg ``use-latest-supported-vec`` was introduced to allow users to
SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
vdev_netvsc, tap, and failsafe drivers combination.
+* **Added a new net driver for Marvell Armada 3k device.**
+
+ Added the new ``mvneta`` net driver for Marvell Armada 3k device. See the
+ :doc:`../nics/mvneta` NIC guide for more details on this new driver.
+
+* **Added NXP ENETC PMD.**
+
+ Added the new enetc driver for NXP enetc platform. See the
+ "ENETC Poll Mode Driver" document for more details on this new driver.
+
+* **Updated Solarflare network PMD.**
+
+ Updated the sfc_efx driver including the following changes:
+
+ * Added support for Rx scatter in EF10 datapath implementation.
+ * Added support for Rx descriptor status API in EF10 datapath implementation.
+ * Added support for TSO in EF10 datapath implementation.
+ * Added support for Tx descriptor status API in EF10 (ef10 and ef10_simple)
+ datapaths implementation.
+
* **Updated failsafe driver.**
Updated the failsafe driver including the following changes:
* Support for runtime Rx and Tx queues setup.
* Support multicast MAC address set.
+* **Added a devarg to use PCAP interface physical MAC address.**
+ A new devarg ``phy_mac`` was introduced to allow users to use physical
+ MAC address of the selected PCAP interface.
+
+* **Added support for GEN3 devices to Intel QAT driver .**
+
+ Added support for the third generation of Intel QuickAssist devices.
+
+* **Updated the QAT PMD.**
+
+ The QAT PMD was updated with additional support for:
+
+ * AES-CMAC algorithm.
+
+* **Updated the AESNI MB PMD.**
+
+ The AESNI MB PMD has been updated with additional support for AES-GCM
+ algorithm support.
+
* **Added Event Ethernet Tx Adapter.**
Added event ethernet Tx adapter library that provides configuration and
the specified port. The port must be stopped before the command call in order
to reconfigure queues.
+* **Add a new sample for vDPA**
+
+ The vdpa sample application creates vhost-user sockets by using the
+ vDPA backend. vDPA stands for vhost Data Path Acceleration which utilizes
+ virtio ring compatible devices to serve virtio driver directly to enable
+ datapath acceleration. As vDPA driver can help to set up vhost datapath,
+ this application doesn't need to launch dedicated worker threads for vhost
+ enqueue/dequeue operations.
+
API Changes
-----------
* eal: The parameters of the function ``rte_devargs_remove()`` have changed
from bus and device names to ``struct rte_devargs``.
+* eal: The scope of ``rte_eal_hotplug_add()``/``rte_dev_probe()``
+ and ``rte_eal_hotplug_remove()``/``rte_dev_remove()`` is extended.
+ In multi-process model, they will guarantee that the device is
+ attached or detached on all processes.
+
* mbuf: The ``__rte_mbuf_raw_free()`` and ``__rte_pktmbuf_prefree_seg()``
functions were deprecated since 17.05 and are replaced by
``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()``.
