Deprecation Notices ------------------- -* 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 is planned for the reta field in struct rte_eth_rss_reta_entry64 - which handles at most 256 entries (8 bits) while newer NICs support larger - tables (512 entries). - It should be integrated in release 2.3. - -* ABI changes are planned for struct rte_eth_fdir_flow in order to support - extend flow director's input set. The release 2.2 does not contain these ABI - changes, but release 2.3 will, and no backwards compatibility is planned. - -* ABI changes are planned for rte_eth_tunnel_filter_conf. Change the fields - of outer_mac and inner_mac from pointer to struct in order to keep the - code's readability. The release 2.2 does not contain these ABI changes, but - release 2.3 will, and no backwards compatibility is planned. - -* The scheduler statistics structure will change to allow keeping track of - RED actions. - -* 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. - -* ABI changes are planned in cmdline buffer size to allow the use of long - commands (such as RETA update in testpmd). This should impact - CMDLINE_PARSE_RESULT_BUFSIZE, STR_TOKEN_SIZE and RDLINE_BUF_SIZE. - It should be integrated in release 2.3. +* 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 VDEV subsystem will be converted as driver 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. + +* 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``
