55 =========================================================
57 * **Add support to offload more flow match and actions for CXGBE PMD**
59 Flow API support has been enhanced for CXGBE Poll Mode Driver to offload:
61 * Match items: destination MAC address.
62 * Action items: push/pop/rewrite vlan header.
64 * **Added a devarg to use the latest supported vector path in i40e.**
65 A new devarg ``use-latest-supported-vec`` was introduced to allow users to
66 choose the latest vector path that the platform supported. For example, users
67 can use AVX2 vector path on BDW/HSW to get better performance.
69 * **Added support for SR-IOV in netvsc PMD.**
71 The ``netvsc`` poll mode driver now supports the Accelerated Networking
72 SR-IOV option in Hyper-V and Azure. This is an alternative to the previous
73 vdev_netvsc, tap, and failsafe drivers combination.
75 * **Updated failsafe driver.**
77 Updated the failsafe driver including the following changes:
79 * Support for Rx queues start and stop.
80 * Support for Rx queues deferred start.
82 * **Added ability to switch queue deferred start flag on testpmd app.**
84 Added a console command to testpmd app, giving ability to switch
85 ``rx_deferred_start`` or ``tx_deferred_start`` flag of the specified queue of
86 the specified port. The port must be stopped before the command call in order
87 to reconfigure queues.
93 .. This section should contain API changes. Sample format:
95 * Add a short 1-2 sentence description of the API change.
96 Use fixed width quotes for ``function_names`` or ``struct_names``.

101 =========================================================
103 * mbuf: The ``__rte_mbuf_raw_free()`` and ``__rte_pktmbuf_prefree_seg()``
104 functions were deprecated since 17.05 and are replaced by
105 ``rte_mbuf_raw_free()`` and ``rte_pktmbuf_prefree_seg()``.
107 * A new device flag, RTE_ETH_DEV_NOLIVE_MAC_ADDR, changes the order of
108 actions inside rte_eth_dev_start regarding MAC set. Some NICs do not
109 support MAC changes once the port has started and with this new device
110 flag the MAC can be properly configured in any case. This is particularly
111 important for bonding.
117 .. This section should contain ABI changes. Sample format:
119 * Add a short 1-2 sentence description of the ABI change
120 that was announced in the previous releases and made in this release.
