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``
|
|
|
|
* eal: An ABI change is planned for 17.11 to make DPDK aware of IOVA address
|
|
translation scheme.
|
|
Reference to phys address in EAL data-structure or functions may change to
|
|
IOVA address or more appropriate name.
|
|
The change will be only for the name.
|
|
Functional aspects of the API or data-structure will remain same.
|
|
|
|
* 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As part of the work, ``ETH_TXQ_FLAGS_NO*`` will be superseded as well.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HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in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.
|
|
|
|
* ethdev: The device flag advertizing hotplug capability
|
|
``RTE_ETH_DEV_DETACHABLE`` is not needed anymore and will be removed in
|
|
v17.11.
|
|
This capability is verified upon calling the relevant hotplug functions in EAL
|
|
by checking that the ``unplug`` ops is set in the bus. This verification is
|
|
done by the EAL and not by the ``ethdev`` layer anymore. Users relying on this
|
|
flag being present only have to remove their checks to follow the change.
|
|
|
|
* ethdev: new parameters - ``rte_security_capabilities`` and
|
|
``rte_security_ops`` will be added to ``rte_eth_dev_info`` and
|
|
``rte_eth_dev`` respectively to support security operations like
|
|
ipsec inline.
|
|
|
|
* cryptodev: new parameters - ``rte_security_capabilities`` and
|
|
``rte_security_ops`` will be added to ``rte_cryptodev_info`` and
|
|
``rte_cryptodev`` respectively to support security protocol offloaded
|
|
operations.
|
|
|
|
* cryptodev: the following function is deprecated starting from 17.08 and will
|
|
be removed in 17.11:
|
|
|
|
- ``rte_cryptodev_create_vdev``
|
|
|
|
* cryptodev: the following function will be static in 17.11 and included
|
|
by all crypto drivers, therefore, will not be public:
|
|
|
|
- ``rte_cryptodev_vdev_pmd_init``
|
|
|
|
* librte_meter: The API will change to accommodate configuration profiles.
|
|
Most of the API functions will have an additional opaque parameter.
