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.
55 * **Added ixgbe preferred Rx/Tx parameters.**
57 Rather than applications providing explicit Rx and Tx parameters such as
58 queue and burst sizes, they can request that the EAL instead uses preferred
59 values provided by the PMD, falling back to defaults within the EAL if the
60 PMD does not provide any. The provision of such tuned values now includes
63 * **Added descriptor status check support for fm10k.**
65 ``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
66 are supported by fm10K.
68 * **Updated the enic driver.**
70 * Add support for mbuf fast free offload.
71 * Add low cycle count Tx handler for no-offload Tx (except mbuf fast free).
72 * Add low cycle count Rx handler for non-scattered Rx.
73 * Minor performance improvements to scattered Rx handler.
74 * Add handlers to add/delete VxLAN port number.
75 * Add devarg to specify ingress VLAN rewrite mode.
81 .. This section should contain API changes. Sample format:
83 * Add a short 1-2 sentence description of the API change.
84 Use fixed width quotes for ``function_names`` or ``struct_names``.

89 =========================================================
91 * Path to runtime config file has changed. The new path is determined as
94 - If DPDK is running as root, ``/var/run/dpdk/<prefix>/config``
95 - If DPDK is not running as root:
97 * If ``$XDG_RUNTIME_DIR`` is set, ``${XDG_RUNTIME_DIR}/dpdk/<prefix>/config``
98 * Otherwise, ``/tmp/dpdk/<prefix>/config``
100 * cryptodev: In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
101 has been replaced with field ``struct rte_device *device``.
102 Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
103 supports an unlimited number of sessions.
104 Two new fields of type ``uint16_t`` have been added:
105 ``min_mbuf_headroom_req`` and ``min_mbuf_tailroom_req``.
106 These parameters specify the recommended headroom and tailroom for mbufs
107 to be processed by the PMD.
109 * cryptodev: Following functions were deprecated and are removed in 18.08:
111 - ``rte_cryptodev_queue_pair_start``
112 - ``rte_cryptodev_queue_pair_stop``
113 - ``rte_cryptodev_queue_pair_attach_sym_session``
114 - ``rte_cryptodev_queue_pair_detach_sym_session``
116 * cryptodev: Following functions were deprecated and are replaced by
117 other functions in 18.08:
119 - ``rte_cryptodev_get_header_session_size`` is replaced with
120 ``rte_cryptodev_sym_get_header_session_size``
121 - ``rte_cryptodev_get_private_session_size`` is replaced with
122 ``rte_cryptodev_sym_get_private_session_size``
124 * cryptodev: Feature flag ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` is
125 replaced with the following more explicit flags:
127 - ``RTE_CRYPTODEV_FF_IN_PLACE_SGL``
128 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT``
129 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT``
130 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT``
131 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT``
133 * cryptodev: Renamed cryptodev experimental APIs:
135 Used user_data instead of private_data in following APIs to avoid confusion
136 with the existing session parameter ``sess_private_data[]`` and related APIs.
138 - ``rte_cryptodev_sym_session_set_private_data()`` changed to
139 ``rte_cryptodev_sym_session_set_user_data()``
140 - ``rte_cryptodev_sym_session_get_private_data()`` changed to
141 ``rte_cryptodev_sym_session_get_user_data()``
143 * compressdev: Feature flag ``RTE_COMP_FF_MBUF_SCATTER_GATHER`` is
144 replaced with the following more explicit flags:
146 - ``RTE_COMP_FF_OOP_SGL_IN_SGL_OUT``
147 - ``RTE_COMP_FF_OOP_SGL_IN_LB_OUT``
148 - ``RTE_COMP_FF_OOP_LB_IN_SGL_OUT``
