Deprecation Notices ------------------- -* 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.
