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 * eal: several API and ABI changes are planned for ``rte_devargs`` in v17.11.
20 The format of device command line parameters will change. The bus will need
21 to be explicitly stated in the device declaration. The enum ``rte_devtype``
22 was used to identify a bus and will disappear.
23 The structure ``rte_devargs`` will change.
24 The ``rte_devargs_list`` will be made private.
25 The following functions are deprecated starting from 17.08 and will either be
26 modified or removed in 17.11:
28 - ``rte_eal_devargs_add``
29 - ``rte_eal_devargs_type_count``
30 - ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
32 * eal: the support of Xen dom0 will be removed from EAL in 17.11; and with
33 that, drivers/net/xenvirt and examples/vhost_xen will also be removed.
35 * eal: An ABI change is planned for 17.11 to make DPDK aware of IOVA address
37 Reference to phys address in EAL data-structure or functions may change to
38 IOVA address or more appropriate name.
39 The change will be only for the name.
40 Functional aspects of the API or data-structure will remain same.
42 * The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
43 are respectively replaced by PKT_RX_VLAN_STRIPPED and
44 PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
45 their behavior will be kept until 17.08 and will be removed in 17.11.
47 * ethdev: Tx offloads will no longer be enabled by default in 17.11.
48 Instead, the ``rte_eth_txmode`` structure will be extended with
49 bit field to enable each Tx offload.
50 Besides of making the Rx/Tx configuration API more consistent for the
51 application, PMDs will be able to provide a better out of the box performance.
52 As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.
54 * ethdev: the legacy filter API, including
55 ``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
56 as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
57 HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
58 PMDs that implement the latter.
59 Target release for removal of the legacy API will be defined once most
60 PMDs have switched to rte_flow.
62 * librte_table: The ``key_mask`` parameter will be added to all the hash tables
63 that currently do not have it, as well as to the hash compute function prototype.
64 The non-"do-sig" versions of the hash tables will be removed
65 (including the ``signature_offset`` parameter)
66 and the "do-sig" versions renamed accordingly.
68 * cryptodev: the following function is deprecated starting from 17.08 and will
71 - ``rte_cryptodev_create_vdev``
