23 .. This section should contain new features added in this release.
26 * **Add a title in the past tense with a full stop.**
28 Add a short 1-2 sentence description in the past tense.
29 The description should be enough to allow someone scanning
30 the release notes to understand the new feature.
32 If the feature adds a lot of sub-features you can use a bullet list
35 * Added feature foo to do something.
36 * Enhanced feature bar to do something else.
38 Refer to the previous release notes for examples.

42 =========================================================
44 * **Added support for Hyper-V netvsc PMD.**
46 The new ``netvsc`` poll mode driver provides native support for
47 networking on Hyper-V. See the :doc:`../nics/netvsc` NIC driver guide
48 for more details on this new driver.
50 * **Added Flow API support for CXGBE PMD.**
52 Flow API support has been added to CXGBE Poll Mode Driver to offload
53 flows to Chelsio T5/T6 NICs. Support added for:
54 * Wildcard (LE-TCAM) and Exact (HASH) match filters.
55 * Match items: physical ingress port, IPv4, IPv6, TCP and UDP.
56 * Action items: queue, drop, count, and physical egress port redirect.
58 * **Added ixgbe preferred Rx/Tx parameters.**
60 Rather than applications providing explicit Rx and Tx parameters such as
61 queue and burst sizes, they can request that the EAL instead uses preferred
62 values provided by the PMD, falling back to defaults within the EAL if the
63 PMD does not provide any. The provision of such tuned values now includes
66 * **Added descriptor status check support for fm10k.**
68 ``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
69 are supported by fm10K.
71 * **Updated the enic driver.**
73 * Add low cycle count Tx handler for no-offload Tx.
74 * Add low cycle count Rx handler for non-scattered Rx.
75 * Minor performance improvements to scattered Rx handler.
76 * Add handlers to add/delete VxLAN port number.
77 * Add devarg to specify ingress VLAN rewrite mode.
79 * **Updated the AESNI MB PMD.**
81 The AESNI MB PMD has been updated with additional support for:
83 * 3DES for 8, 16 and 24 byte keys.
85 * **Added a new compression PMD using Intel's QuickAssist (QAT) device family.**
87 Added the new ``QAT`` compression driver, for compression and decompression
88 operations in software. See the :doc:`../compressdevs/qat_comp` compression
89 driver guide for details on this new driver.
91 * **Updated the ISA-L PMD.**
93 Added support for chained mbufs (input and output).
99 .. This section should contain API changes. Sample format:
101 * Add a short 1-2 sentence description of the API change.
102 Use fixed width quotes for ``function_names`` or ``struct_names``.
105 This section is a comment. Do not overwrite or remove it.
106 Also, make sure to start the actual text at the margin.
107 =========================================================
109 * Path to runtime config file has changed. The new path is determined as
112 - If DPDK is running as root, ``/var/run/dpdk/<prefix>/config``
113 - If DPDK is not running as root:
115 * If ``$XDG_RUNTIME_DIR`` is set, ``${XDG_RUNTIME_DIR}/dpdk/<prefix>/config``
116 * Otherwise, ``/tmp/dpdk/<prefix>/config``
118 * cryptodev: In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
119 has been replaced with field ``struct rte_device *device``.
120 Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
121 supports an unlimited number of sessions.
122 Two new fields of type ``uint16_t`` have been added:
123 ``min_mbuf_headroom_req`` and ``min_mbuf_tailroom_req``.
124 These parameters specify the recommended headroom and tailroom for mbufs
125 to be processed by the PMD.
127 * cryptodev: Following functions were deprecated and are removed in 18.08:
129 - ``rte_cryptodev_queue_pair_start``
130 - ``rte_cryptodev_queue_pair_stop``
131 - ``rte_cryptodev_queue_pair_attach_sym_session``
132 - ``rte_cryptodev_queue_pair_detach_sym_session``
134 * cryptodev: Following functions were deprecated and are replaced by
135 other functions in 18.08:
137 - ``rte_cryptodev_get_header_session_size`` is replaced with
138 ``rte_cryptodev_sym_get_header_session_size``
139 - ``rte_cryptodev_get_private_session_size`` is replaced with
140 ``rte_cryptodev_sym_get_private_session_size``
142 * cryptodev: Feature flag ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` is
143 replaced with the following more explicit flags:
145 - ``RTE_CRYPTODEV_FF_IN_PLACE_SGL``
146 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT``
147 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT``
148 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT``
149 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT``
151 * cryptodev: Renamed cryptodev experimental APIs:
153 Used user_data instead of private_data in following APIs to avoid confusion
154 with the existing session parameter ``sess_private_data[]`` and related APIs.
156 - ``rte_cryptodev_sym_session_set_private_data()`` changed to
157 ``rte_cryptodev_sym_session_set_user_data()``
158 - ``rte_cryptodev_sym_session_get_private_data()`` changed to
159 ``rte_cryptodev_sym_session_get_user_data()``
161 * compressdev: Feature flag ``RTE_COMP_FF_MBUF_SCATTER_GATHER`` is
162 replaced with the following more explicit flags:
164 - ``RTE_COMP_FF_OOP_SGL_IN_SGL_OUT``
165 - ``RTE_COMP_FF_OOP_SGL_IN_LB_OUT``
166 - ``RTE_COMP_FF_OOP_LB_IN_SGL_OUT``
