44 * **Added Flow API support for CXGBE PMD.**
46 Flow API support has been added to CXGBE Poll Mode Driver to offload
47 flows to Chelsio T5/T6 NICs.
49 * **Added ixgbe preferred Rx/Tx parameters.**
51 Rather than applications providing explicit Rx and Tx parameters such as
52 queue and burst sizes, they can request that the EAL instead uses preferred
53 values provided by the PMD, falling back to defaults within the EAL if the
54 PMD does not provide any. The provision of such tuned values now includes
57 * **Added descriptor status check support for fm10k.**
59 ``rte_eth_rx_descritpr_status`` and ``rte_eth_tx_descriptor_status``
60 are supported by fm10K.
62 * **Updated the enic driver.**
64 * Add support for mbuf fast free offload.
65 * Add low cycle count Tx handler for no-offload Tx (except mbuf fast free).
66 * Add low cycle count Rx handler for non-scattered Rx.
67 * Minor performance improvements to scattered Rx handler.
68 * Add handlers to add/delete VxLAN port number.
69 * Add devarg to specify ingress VLAN rewrite mode.
75 .. This section should contain API changes. Sample format:
77 * Add a short 1-2 sentence description of the API change.

85 * cryptodev: In struct ``struct rte_cryptodev_info``, field ``rte_pci_device *pci_dev``
86 has been replaced with field ``struct rte_device *device``.
87 Value 0 is accepted in ``sym.max_nb_sessions``, meaning that a device
88 supports an unlimited number of sessions.
89 Two new fields of type ``uint16_t`` have been added:
90 ``min_mbuf_headroom_req`` and ``min_mbuf_tailroom_req``.
91 These parameters specify the recommended headroom and tailroom for mbufs
92 to be processed by the PMD.
94 * cryptodev: Following functions were deprecated and are removed in 18.08:
96 - ``rte_cryptodev_queue_pair_start``
97 - ``rte_cryptodev_queue_pair_stop``
98 - ``rte_cryptodev_queue_pair_attach_sym_session``
99 - ``rte_cryptodev_queue_pair_detach_sym_session``
101 * cryptodev: Following functions were deprecated and are replaced by
102 other functions in 18.08:
104 - ``rte_cryptodev_get_header_session_size`` is replaced with
105 ``rte_cryptodev_sym_get_header_session_size``
106 - ``rte_cryptodev_get_private_session_size`` is replaced with
107 ``rte_cryptodev_sym_get_private_session_size``
109 * cryptodev: Feature flag ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` is
110 replaced with the following more explicit flags:
111 - ``RTE_CRYPTODEV_FF_IN_PLACE_SGL``
112 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_SGL_OUT``
113 - ``RTE_CRYPTODEV_FF_OOP_SGL_IN_LB_OUT``
114 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_SGL_OUT``
115 - ``RTE_CRYPTODEV_FF_OOP_LB_IN_LB_OUT``
117 * cryptodev: Renamed cryptodev experimental APIs:
119 Used user_data instead of private_data in following APIs to avoid confusion
120 with the existing session parameter ``sess_private_data[]`` and related APIs.
121 ``rte_cryptodev_sym_session_set_private_data()`` changed to
122 ``rte_cryptodev_sym_session_set_user_data()``
123 ``rte_cryptodev_sym_session_get_private_data()`` changed to
124 ``rte_cryptodev_sym_session_get_user_data()``
126 * compressdev: Feature flag ``RTE_COMP_FF_MBUF_SCATTER_GATHER`` is
127 replaced with the following more explicit flags:
128 - ``RTE_COMP_FF_OOP_SGL_IN_SGL_OUT``
