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 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
-
-* 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_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 17.08:
+
+ - ``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``
+
+* 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 17.05.
+
+* vfio: Some functions are planned to be exported outside librte_eal in 17.05.
+ VFIO APIs like ``vfio_setup_device``, ``vfio_get_group_fd`` can be used by
+ subsystem other than EAL/PCI. For that, these need to be exported symbols.
+ Such APIs are planned to be renamed according to ``rte_*`` naming convention
+ and exported from librte_eal.
+
+* The PCI and VDEV subsystems will be converted as drivers of the new bus model.
+ It will imply some EAL API changes in 17.05.
+
+* ``eth_driver`` is planned to be removed in 17.05. 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``. Similarly, ``rte_pci_driver`` is planned to be removed from
+ ``rte_cryptodev_driver`` in 17.05.
+
+* ethdev: An API change is planned for 17.05 for the function
+ ``_rte_eth_dev_callback_process``. In 17.05 the function will return an ``int``
+ instead of ``void`` and a fourth parameter ``void *ret_param`` will be added.
+
+* ethdev: for 17.05 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``.
+
+ The following fields will be removed from ``struct eth_dev_ops``:
+
+ ``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``.
+
+ The functions will be renamed to the following, and moved to the ``ixgbe`` PMD:
+
+ ``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 17.02 and will be removed in 17.05.
+
+* 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.
