Deprecation Notices
-------------------
-* 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.
-
-* 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.
+* 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``
+
+* 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 16.11 and will be removed in 17.02.
+ 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``
-* 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.
+* librte_meter: The API will change to accommodate configuration profiles.
+ Most of the API functions will have an additional opaque parameter.
-* 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.
+* 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.
