Deprecation Notices
-------------------
+* eal: the following functions are deprecated starting from 17.05 and will
+ be removed in 17.08:
+
+ - ``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.
+
* igb_uio: iomem mapping and sysfs files created for iomem and ioport in
igb_uio will be removed, because we are able to detect these from what Linux
has exposed, like the way we have done with uio-pci-generic. This change
- targets release 17.02.
-
-* ABI/API changes are planned for 17.02: ``rte_device``, ``rte_driver`` will be
- impacted because of introduction of a new ``rte_bus`` hierarchy. This would
- also impact the way devices are identified by EAL. A bus-device-driver model
- will be introduced providing a hierarchical view of devices.
-
-* ``eth_driver`` is planned to be removed in 17.02. This currently serves as
- a placeholder for PMDs to register themselves. Changes for ``rte_bus`` will
- provide a way to handle device initialization currently being done in
- ``eth_driver``.
-
-* In 17.02 ABI changes are planned: the ``rte_eth_dev`` structure will be
- extended with new function pointer ``tx_pkt_prepare`` allowing verification
- and processing of packet burst to meet HW specific requirements before
- transmit. Also new fields will be added to the ``rte_eth_desc_lim`` structure:
- ``nb_seg_max`` and ``nb_mtu_seg_max`` providing information about number of
- segments limit to be transmitted by device for TSO/non-TSO packets.
-
-* In 17.02 ABI change is planned: the ``rte_eth_dev_info`` structure
- will be extended with a new member ``fw_version`` in order to store
- the NIC firmware version.
-
-* ethdev: an API change is planned for 17.02 for the function
- ``_rte_eth_dev_callback_process``. In 17.02 the function will return an ``int``
- instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
+ targets release 17.05.
-* ethdev: for 17.02 it is planned to deprecate the following five functions
- and move them in ixgbe:
+* The VDEV subsystem will be converted as driver of the new bus model.
+ It may imply some EAL API changes in 17.08.
- ``rte_eth_dev_set_vf_rxmode``
+* The struct ``rte_pci_driver`` is planned to be removed from
+ ``rte_cryptodev_driver`` and ``rte_eventdev_driver`` in 17.08.
- ``rte_eth_dev_set_vf_rx``
+* ethdev: An API change is planned for 17.08 for the function
+ ``_rte_eth_dev_callback_process``. In 17.08 the function will return an ``int``
+ instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
+
+* ethdev: for 17.08 it is planned to deprecate the following nine rte_eth_dev_*
+ functions and move them into the ixgbe PMD:
+
+ ``rte_eth_dev_bypass_init``, ``rte_eth_dev_bypass_state_set``,
+ ``rte_eth_dev_bypass_state_show``, ``rte_eth_dev_bypass_event_store``,
+ ``rte_eth_dev_bypass_event_show``, ``rte_eth_dev_wd_timeout_store``,
+ ``rte_eth_dev_bypass_wd_timeout_show``, ``rte_eth_dev_bypass_ver_show``,
+ ``rte_eth_dev_bypass_wd_reset``.
- ``rte_eth_dev_set_vf_tx``
+ The following fields will be removed from ``struct eth_dev_ops``:
- ``rte_eth_dev_set_vf_vlan_filter``
+ ``bypass_init_t``, ``bypass_state_set_t``, ``bypass_state_show_t``,
+ ``bypass_event_set_t``, ``bypass_event_show_t``, ``bypass_wd_timeout_set_t``,
+ ``bypass_wd_timeout_show_t``, ``bypass_ver_show_t``, ``bypass_wd_reset_t``.
- ``rte_eth_set_vf_rate_limit``
+ The functions will be renamed to the following, and moved to the ``ixgbe`` PMD:
-* ABI changes are planned for 17.02 in the ``rte_mbuf`` structure: some fields
- may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
- ``nb_segs`` in one operation, because some platforms have an overhead if the
- store address is not naturally aligned. Other mbuf fields, such as the
- ``port`` field, may be moved or removed as part of this mbuf work. A
- ``timestamp`` will also be added.
+ ``rte_pmd_ixgbe_bypass_init``, ``rte_pmd_ixgbe_bypass_state_set``,
+ ``rte_pmd_ixgbe_bypass_state_show``, ``rte_pmd_ixgbe_bypass_event_set``,
+ ``rte_pmd_ixgbe_bypass_event_show``, ``rte_pmd_ixgbe_bypass_wd_timeout_set``,
+ ``rte_pmd_ixgbe_bypass_wd_timeout_show``, ``rte_pmd_ixgbe_bypass_ver_show``,
+ ``rte_pmd_ixgbe_bypass_wd_reset``.
* 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 16.11 and will be removed in 17.02.
-
-* mempool: The functions ``rte_mempool_count`` and ``rte_mempool_free_count``
- will be removed in 17.02.
- They are replaced by ``rte_mempool_avail_count`` and
- ``rte_mempool_in_use_count`` respectively.
-
-* mempool: The functions for single/multi producer/consumer are deprecated
- and will be removed in 17.02.
- It is replaced by ``rte_mempool_generic_get/put`` functions.
+ their behavior will be kept until 17.05 and will be removed in 17.08.
+
+* ethdev: Tx offloads will no longer be enabled by default in 17.08.
+ 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.
+
+* cryptodev: All PMD names definitions will be moved to the individual PMDs
+ in 17.08.
+
+* cryptodev: The following changes will be done in in 17.08:
+
+ - the device type enumeration ``rte_cryptodev_type`` will be removed
+ - the following structures will be changed: ``rte_cryptodev_session``,
+ ``rte_cryptodev_sym_session``, ``rte_cryptodev_info``, ``rte_cryptodev``
+ - the function ``rte_cryptodev_count_devtype`` will be replaced by
+ ``rte_cryptodev_device_count_by_driver``
+
+* cryptodev: API changes are planned for 17.08 for the sessions management
+ to make it agnostic to the underlying devices, removing coupling with
+ crypto PMDs, so a single session can be used on multiple devices.
+
+ - ``struct rte_cryptodev_sym_session``, dev_id, dev_type will be removed,
+ _private field changed to the indirect array of private data pointers of
+ all supported devices
+
+ An API of followed functions will be changed to allow operate on multiple
+ devices with one session:
+
+ - ``rte_cryptodev_sym_session_create``
+ - ``rte_cryptodev_sym_session_free``
+ - ``rte_cryptodev_sym_session_pool_create``
+
+ While dev_id will not be stored in the ``struct rte_cryptodev_sym_session``,
+ directly, the change of followed API is required:
+
+ - ``rte_cryptodev_queue_pair_attach_sym_session``
+ - ``rte_cryptodev_queue_pair_detach_sym_session``
+
+* cryptodev: the structures ``rte_crypto_op``, ``rte_crypto_sym_op``
+ and ``rte_crypto_sym_xform`` will be restructured in 17.08,
+ for correctness and improvement.
+
+* crypto/scheduler: the following two functions are deprecated starting
+ from 17.05 and will be removed in 17.08:
+
+ - ``rte_crpytodev_scheduler_mode_get``, replaced by ``rte_cryptodev_scheduler_mode_get``
+ - ``rte_crpytodev_scheduler_mode_set``, replaced by ``rte_cryptodev_scheduler_mode_set``
+
+* 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.
