SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
vdev_netvsc, tap, and failsafe drivers combination.
+* **Updated failsafe driver.**
+
+ Updated the failsafe driver including the following changes:
+
+ * Support for Rx and Tx queues start and stop.
+ * Support for Rx and Tx queues deferred start.
+ * Support for runtime Rx and Tx queues setup.
+ * Support multicast MAC address set.
+
+* **Added Event Ethernet Tx Adapter.**
+
+ Added event ethernet Tx adapter library that provides configuration and
+ data path APIs for the ethernet transmit stage of an event driven packet
+ processing application. These APIs abstract the implementation of the
+ transmit stage and allow the application to use eventdev PMD support or
+ a common implementation.
+
+* **Added Distributed Software Eventdev PMD.**
+
+ Added the new Distributed Software Event Device (DSW), which is a
+ pure-software eventdev driver distributing the work of scheduling
+ among all eventdev ports and the lcores using them. DSW, compared to
+ the SW eventdev PMD, sacrifices load balancing performance to
+ gain better event scheduling throughput and scalability.
+
+* **Added ability to switch queue deferred start flag on testpmd app.**
+
+ Added a console command to testpmd app, giving ability to switch
+ ``rx_deferred_start`` or ``tx_deferred_start`` flag of the specified queue of
+ the specified port. The port must be stopped before the command call in order
+ to reconfigure queues.

API Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eal: ``rte_memseg_list`` structure now has an additional flag indicating
+ whether the memseg list is externally allocated. This will have implications
+ for any users of memseg-walk-related functions, as they will now have to skip
+ externally allocated segments in most cases if the intent is to only iterate
+ over internal DPDK memory.
+
* 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()``.
flag the MAC can be properly configured in any case. This is particularly
important for bonding.
+* The default behaviour of CRC strip offload changed. Without any specific Rx
+ offload flag, default behavior by PMD is now to strip CRC.
+ DEV_RX_OFFLOAD_CRC_STRIP offload flag has been removed.
+ To request keeping CRC, application should set ``DEV_RX_OFFLOAD_KEEP_CRC`` Rx
+ offload.
+
+* eventdev: Type of 2nd parameter to ``rte_event_eth_rx_adapter_caps_get()``
+ has been changed from uint8_t to uint16_t.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=========================================================
+* eal: added ``legacy_mem`` and ``single_file_segments`` values to
+ ``rte_config`` structure on account of improving DPDK usability when
+ using either ``--legacy-mem`` or ``--single-file-segments`` flags.
+
+* eal: EAL library ABI version was changed due to previously announced work on
+ supporting external memory in DPDK:
+ - structure ``rte_memseg_list`` now has a new field indicating length
+ of memory addressed by the segment list
+ - structure ``rte_memseg_list`` now has a new flag indicating whether
+ the memseg list refers to external memory
