Deprecation Notices
-------------------
-* The EAL function pci_config_space_set is deprecated in release 16.04
- and will be removed from 16.07.
- Macros CONFIG_RTE_PCI_CONFIG, CONFIG_RTE_PCI_EXTENDED_TAG and
- CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE will be removed.
- The /sys entries extended_tag and max_read_request_size created by igb_uio
- will be removed.
-
-* The following fields have been deprecated in rte_eth_stats:
- ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
- tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
-
-* ABI changes are planned for adding four new flow types. This impacts
- RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
- but release 2.3 will. [postponed]
-
-* ABI change is planned for the rte_mempool structure to allow mempool
- cache support to be dynamic depending on the mempool being created
- needing cache support. Saves about 1.5M of memory per rte_mempool structure
- by removing the per lcore cache memory. Change will occur in DPDK 16.07
- release and will skip the define RTE_NEXT_ABI in DPDK 16.04 release. The
- code affected is app/test/test_mempool.c and librte_mempool/rte_mempool.[ch].
- The rte_mempool.local_cache will be converted from an array to a pointer to
- allow for dynamic allocation of the per lcore cache memory.
-
-* The rte_mempool struct will be changed in 16.07 to facilitate the new
- external mempool manager functionality.
- The ring element will be replaced with a more generic 'pool' opaque pointer
- to allow new mempool handlers to use their own user-defined mempool
- layout. Also newly added to rte_mempool is a handler index.
- The existing API will be backward compatible, but there will be new API
- functions added to facilitate the creation of mempools using an external
- handler. The 16.07 release will contain these changes.
-
-* The rte_mempool allocation will be changed in 16.07:
- allocation of large mempool in several virtual memory chunks, new API
- to populate a mempool, new API to free a mempool, allocation in
- anonymous mapping, drop of specific dom0 code. These changes will
- induce a modification of the rte_mempool structure, plus a
- modification of the API of rte_mempool_obj_iter(), implying a breakage
- of the ABI.
+* 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 17.05.
+
+* The VDEV subsystem will be converted as driver of the new bus model.
+ It may imply some EAL API changes in 17.08.
+
+* The struct ``rte_pci_driver`` is planned to be removed from
+ ``rte_cryptodev_driver`` and ``rte_eventdev_driver`` in 17.08.
+
+* 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``.
+
+ 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 17.05 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``
+
+* 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``
