ABI and API Deprecation
=======================
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: several API and ABI changes are planned for ``rte_devargs`` in v17.11.
The format of device command line parameters will change. The bus will need
to be explicitly stated in the device declaration. The enum ``rte_devtype``
was used to identify a bus and will disappear.
The structure ``rte_devargs`` will change.
The ``rte_devargs_list`` will be made private.
The following functions are deprecated starting from 17.08 and will either be
modified or removed in 17.11:
- ``rte_eal_devargs_add``
- ``rte_eal_devargs_type_count``
- ``rte_eal_parse_devargs_str``, replaced by ``rte_eal_devargs_parse``
* pci: Several exposed functions are misnamed.
The following functions are deprecated starting from v17.11 and are replaced:
- ``eal_parse_pci_BDF`` replaced by ``rte_pci_addr_parse``
- ``eal_parse_pci_DomBDF`` replaced by ``rte_pci_addr_parse``
- ``rte_eal_compare_pci_addr`` replaced by ``rte_pci_addr_cmp``
* 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As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.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HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in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_meter: The API will change to accommodate configuration profiles.
Most of the API functions will have an additional opaque parameter.
