45 =========================================================
47 * **Added support for Hyper-V netvsc PMD.**
49 The new ``netvsc`` poll mode driver provides native support for
50 networking on Hyper-V. See the :doc:`../nics/netvsc` NIC driver guide
51 for more details on this new driver.
53 * **Added Flow API support for CXGBE PMD.**
55 Flow API support has been added to CXGBE Poll Mode Driver to offload
56 flows to Chelsio T5/T6 NICs. Support added for:
58 * Wildcard (LE-TCAM) and Exact (HASH) match filters.
59 * Match items: physical ingress port, IPv4, IPv6, TCP and UDP.
60 * Action items: queue, drop, count, and physical egress port redirect.
62 * **Added ixgbe preferred Rx/Tx parameters.**
64 Rather than applications providing explicit Rx and Tx parameters such as
65 queue and burst sizes, they can request that the EAL instead uses preferred
66 values provided by the PMD, falling back to defaults within the EAL if the
67 PMD does not provide any. The provision of such tuned values now includes
70 * **Added descriptor status check support for fm10k.**
72 The ``rte_eth_rx_descriptor_status`` and ``rte_eth_tx_descriptor_status``
73 APIs are now supported by fm10K.
75 * **Updated the enic driver.**
77 * Add low cycle count Tx handler for no-offload Tx.
78 * Add low cycle count Rx handler for non-scattered Rx.
79 * Minor performance improvements to scattered Rx handler.
80 * Add handlers to add/delete VxLAN port number.
81 * Add devarg to specify ingress VLAN rewrite mode.
83 * **Updated mlx5 driver.**
85 Updated the mlx5 driver including the following changes:
87 * Added port representors support.
88 * Added Flow API support for e-switch rules.
89 Added support for ACTION_PORT_ID, ACTION_DROP, ACTION_OF_POP_VLAN,
90 ACTION_OF_PUSH_VLAN, ACTION_OF_SET_VLAN_VID, ACTION_OF_SET_VLAN_PCP
92 * Added support for 32-bit compilation.
94 * **Added TSO support for the mlx4 driver.**
96 Added TSO support for the mlx4 drivers from MLNX_OFED_4.4 and above.
98 * **SoftNIC PMD rework.**
100 The SoftNIC PMD infrastructure has been restructured to use the Packet
101 Framework, which makes it more flexible, modular and easier to add new
102 functionality in the future.
104 * **Updated the AESNI MB PMD.**
106 The AESNI MB PMD has been updated with additional support for:
108 * 3DES for 8, 16 and 24 byte keys.
110 * **Added a new compression PMD using Intel's QuickAssist (QAT) device family.**
112 Added the new ``QAT`` compression driver, for compression and decompression
113 operations in software. See the :doc:`../compressdevs/qat_comp` compression
114 driver guide for details on this new driver.
116 * **Updated the ISA-L PMD.**
118 Added support for chained mbufs (input and output).
124 .. This section should contain API changes. Sample format:
126 * Add a short 1-2 sentence description of the API change.
127 Use fixed width quotes for ``function_names`` or ``struct_names``.

131 Also, make sure to start the actual text at the margin.
132 =========================================================
134 * The path to the runtime config file has changed. The new path is determined
137 - If DPDK is running as root, ``/var/run/dpdk/<prefix>/config``
138 - If DPDK is not running as root:
140 * If ``$XDG_RUNTIME_DIR`` is set, ``${XDG_RUNTIME_DIR}/dpdk/<prefix>/config``
141 * Otherwise, ``/tmp/dpdk/<prefix>/config``
143 * eal: The function ``rte_eal_mbuf_default_mempool_ops`` was deprecated
144 and is removed in 18.08. It shall be replaced by
145 ``rte_mbuf_best_mempool_ops``.
147 * mempool: Following functions were deprecated and are removed in 18.08:
149 - ``rte_mempool_populate_iova_tab``
150 - ``rte_mempool_populate_phys_tab``
151 - ``rte_mempool_populate_phys`` (``rte_mempool_populate_iova`` should be used)
152 - ``rte_mempool_virt2phy`` (``rte_mempool_virt2iova`` should be used)
153 - ``rte_mempool_xmem_create``
154 - ``rte_mempool_xmem_size``
155 - ``rte_mempool_xmem_usage``
157 * ethdev: The old offload API is removed:
159 - Rx per-port ``rte_eth_conf.rxmode.[bit-fields]``
160 - Tx per-queue ``rte_eth_txconf.txq_flags``
161 - ``ETH_TXQ_FLAGS_NO*``
163 The transition bits are removed:
165 - ``rte_eth_conf.rxmode.ignore_offload_bitfield``
166 - ``ETH_TXQ_FLAGS_IGNORE``
168 * cryptodev: The following API changes have been made in 18.08:
170 - In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
171 has been replaced with field ``struct rte_device *device``.
172 - Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
173 supports an unlimited number of sessions.
174 - Two new fields of type ``uint16_t`` have been added:
175 ``min_mbuf_headroom_req`` and ``min_mbuf_tailroom_req``. These parameters
176 specify the recommended headroom and tailroom for mbufs to be processed by
179 * cryptodev: The following functions were deprecated and are removed in 18.08:
181 - ``rte_cryptodev_queue_pair_start``
182 - ``rte_cryptodev_queue_pair_stop``
183 - ``rte_cryptodev_queue_pair_attach_sym_session``

198 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT``
199 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT``
200 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT``
201 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT``
203 * cryptodev: Renamed cryptodev experimental APIs:
205 Used user_data instead of private_data in following APIs to avoid confusion
206 with the existing session parameter ``sess_private_data[]`` and related APIs.
208 - ``rte_cryptodev_sym_session_set_private_data()`` changed to
209 ``rte_cryptodev_sym_session_set_user_data()``
210 - ``rte_cryptodev_sym_session_get_private_data()`` changed to
211 ``rte_cryptodev_sym_session_get_user_data()``
