=======================

See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
|
|
API and ABI deprecation notices are to be posted here.

Deprecation Notices
|
|
-------------------
|
|
|
|
* eal: the following functions are deprecated starting from 17.05 and will
|
|
be removed in 17.11:
|
|
|
|
- ``rte_set_log_level``, replaced by ``rte_log_set_global_level``
|
|
- ``rte_get_log_level``, replaced by ``rte_log_get_global_level``
|
|
- ``rte_set_log_type``, replaced by ``rte_log_set_level``
|
|
- ``rte_get_log_type``, replaced by ``rte_log_get_level``
|
|
|
|
* devargs: An ABI change is planned for 17.08 for the structure ``rte_devargs``.
|
|
The current version is dependent on bus-specific device identifier, which will
|
|
be made generic and abstracted, in order to make the EAL bus-agnostic.
|
|
|
|
Accompanying this evolution, device command line parameters will thus support
|
|
explicit bus definition in a device declaration.
|
|
|
|
* The VDEV subsystem will be converted as driver of the new bus model.
|
|
It may imply some EAL API changes in 17.08.
|
|
|
|
* The struct ``rte_pci_driver`` is planned to be removed from
|
|
``rte_cryptodev_driver`` and ``rte_eventdev_driver`` in 17.08.
|
|
|
|
* The mbuf flags PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated and
|
|
are respectively replaced by PKT_RX_VLAN_STRIPPED and
|
|
PKT_RX_QINQ_STRIPPED, that are better described. The old flags and
|
|
their behavior will be kept until 17.08 and will be removed in 17.11.
|
|
|
|
* ethdev: Tx offloads will no longer be enabled by default in 17.11.
|
|
Instead, the ``rte_eth_txmode`` structure will be extended with
|
|
bit field to enable each Tx offload.
|
|
Besides of making the Rx/Tx configuration API more consistent for the
|
|
application, PMDs will be able to provide a better out of the box performance.
|
|
As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.
|
|
|
|
* ethdev: the legacy filter API, including
|
|
``rte_eth_dev_filter_supported()``, ``rte_eth_dev_filter_ctrl()`` as well
|
|
as filter types MACVLAN, ETHERTYPE, FLEXIBLE, SYN, NTUPLE, TUNNEL, FDIR,
|
|
HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in
|
|
PMDs that implement the latter.
|
|
Target release for removal of the legacy API will be defined once most
|
|
PMDs have switched to rte_flow.
|
|
|
|
* librte_table: The ``key_mask`` parameter will be added to all the hash tables
|
|
that currently do not have it, as well as to the hash compute function prototype.
|
|
The non-"do-sig" versions of the hash tables will be removed
|
|
(including the ``signature_offset`` parameter)
|
|
and the "do-sig" versions renamed accordingly.
|
|
|
|
* eal: the following function is deprecated starting from 17.08 and will
|
|
be removed in 17.11:
|
|
|
|
- ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
|
|
|
|
* cryptodev: the following function is deprecated starting from 17.08 and will
|
|
be removed in 17.11:
|
|
|
|
- ``rte_cryptodev_create_vdev``
|
