1 ABI and API Deprecation
2 =======================
4 See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
5 API and ABI deprecation notices are to be posted here.
11 * eal: the following functions are deprecated starting from 17.05 and will
14 - ``rte_set_log_level``, replaced by ``rte_log_set_global_level``
15 - ``rte_get_log_level``, replaced by ``rte_log_get_global_level``
16 - ``rte_set_log_type``, replaced by ``rte_log_set_level``
17 - ``rte_get_log_type``, replaced by ``rte_log_get_level``
19 * devargs: An ABI change is planned for 17.08 for the structure ``rte_devargs``.
20 The current version is dependent on bus-specific device identifier, which will
21 be made generic and abstracted, in order to make the EAL bus-agnostic.
23 Accompanying this evolution, device command line parameters will thus support
24 explicit bus definition in a device declaration.
26 * The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
27 are respectively replaced by PKT_RX_VLAN_STRIPPED and
28 PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
29 their behavior will be kept until 17.08 and will be removed in 17.11.
31 * ethdev: Tx offloads will no longer be enabled by default in 17.11.
32 Instead, the ``rte_eth_txmode`` structure will be extended with
33 bit field to enable each Tx offload.
34 Besides of making the Rx/Tx configuration API more consistent for the
35 application, PMDs will be able to provide a better out of the box performance.
36 As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.
38 * ethdev: the legacy filter API, including
39 ``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
40 as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
41 HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
42 PMDs that implement the latter.
43 Target release for removal of the legacy API will be defined once most
44 PMDs have switched to rte_flow.
46 * librte_table: The ``key_mask`` parameter will be added to all the hash tables
47 that currently do not have it, as well as to the hash compute function prototype.
48 The non-"do-sig" versions of the hash tables will be removed
49 (including the ``signature_offset`` parameter)
50 and the "do-sig" versions renamed accordingly.
52 * eal: the following function is deprecated starting from 17.08 and will
55 - ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
57 * cryptodev: the following function is deprecated starting from 17.08 and will
60 - ``rte_cryptodev_create_vdev``
