Deprecation Notices
-------------------
-* Significant ABI changes are planned for struct rte_eth_dev to support up to
- 1024 queues per port. This change will be in release 2.2.
- There is no backward compatibility planned from release 2.2.
- All binaries will need to be rebuilt from release 2.2.
-
-* The Macros RTE_HASH_BUCKET_ENTRIES_MAX and RTE_HASH_KEY_LENGTH_MAX are
- deprecated and will be removed with version 2.2.
-
-* The function rte_jhash2 is deprecated and should be removed.
-
-* The following fields have been deprecated in rte_eth_stats:
- imissed, ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
- tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
-
-* API for flow director filters has been replaced by rte_eth_dev_filter_ctrl.
- Following old API is deprecated and will be removed with version 2.2 without
- backward compatibility.
- Functions: rte_eth_dev_fdir_*.
- Structures: rte_fdir_*, rte_eth_fdir.
- Enums: rte_l4type, rte_iptype.
-
-* ABI changes are planned for struct rte_eth_fdir_flow_ext in order to support
- flow director filtering in VF. The release 2.1 does not contain these ABI
- changes, but release 2.2 will, and no backwards compatibility is planned.
-
-* ABI changes are planned for struct rte_eth_fdir_filter and
- rte_eth_fdir_masks in order to support new flow director modes,
- MAC VLAN and Cloud, on x550. The MAC VLAN mode means the MAC and
- VLAN are monitored. The Cloud mode is for VxLAN and NVGRE, and
- the tunnel type, TNI/VNI, inner MAC and inner VLAN are monitored.
- The release 2.2 will contain these changes without backwards compatibility.
-
-* ABI changes are planned for struct virtio_net in order to support vhost-user
- multiple queues feature.
- It should be integrated in release 2.2 without backward compatibility.
-
-* The scheduler hierarchy structure (rte_sched_port_hierarchy) will change to
- allow for a larger number of subport entries.
- The number of available traffic_classes and queues may also change.
- The mbuf structure element for sched hierarchy will also change from a single
- 32 bit to a 64 bit structure.
-
-* The scheduler statistics structure will change to allow keeping track of
- RED actions.
-
-* librte_cfgfile: In order to allow for longer names and values,
- the value of macros CFG_NAME_LEN and CFG_NAME_VAL will be increased.
- Most likely, the new values will be 64 and 256, respectively.
-
-* librte_port: Macros to access the packet meta-data stored within the
- packet buffer will be adjusted to cover the packet mbuf structure as well,
- as currently they are able to access any packet buffer location except the
- packet mbuf structure.
-
-* librte_table LPM: A new parameter to hold the table name will be added to
- the LPM table parameter structure.
-
-* librte_table: New functions for table entry bulk add/delete will be added
- to the table operations structure.
-
-* librte_table hash: Key mask parameter will be added to the hash table
- parameter structure for 8-byte key and 16-byte key extendible bucket and
- LRU tables.
-
-* librte_pipeline: The prototype for the pipeline input port, output port
- and table action handlers will be updated:
- the pipeline parameter will be added, the packets mask parameter will be
- either removed (for input port action handler) or made input-only.
+* 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: the support of Xen dom0 will be removed from EAL in 17.11; and with
+ that, drivers/net/xenvirt and examples/vhost_xen will also be removed.
+
+* 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.
+
+* mempool: The following will be modified in 17.11:
+
+ - ``rte_mempool_xmem_size`` and ``rte_mempool_xmem_usage`` need to know
+ the mempool flag status so adding new param rte_mempool in those API.
+ - Removing __rte_unused int flag param from ``rte_mempool_generic_put``
+ and ``rte_mempool_generic_get`` API.
+ - ``rte_mempool`` flags data type will changed from int to
+ unsigned int.
+
+* 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.
+
+* ABI/API changes are planned for 17.11 in all structures which include port_id
+ definition such as "rte_eth_dev_data", "rte_port_ethdev_reader_params",
+ "rte_port_ethdev_writer_params", and so on. The definition of port_id will be
+ changed from 8 bits to 16 bits in order to support more than 256 ports in
+ DPDK. All APIs which have port_id parameter will be changed at the same time.
+
+* ethdev: An ABI change is planned for 17.11 for the structure rte_eth_dev_data.
+ The size of the unique name will increase RTE_ETH_NAME_MAX_LEN from 32 to
+ 64 characters to allow using a globally unique identifier (GUID) in this field.
+
+* 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``
+
+* cryptodev: the following function will have an extra parameter, passing a
+ statically allocated crypto driver structure, instead of calling malloc,
+ in 17.11:
+
+ - ``rte_cryptodev_allocate_driver``
+
+* 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.
