ABI and API Deprecation ======================= See the :doc:`guidelines document for details of the ABI policy `. API and ABI deprecation notices are to be posted here. Deprecation Notices ------------------- * The log history is deprecated. It is voided in 16.07 and will be removed in release 16.11. * The ethdev hotplug API is going to be moved to EAL with a notification mechanism added to crypto and ethdev libraries so that hotplug is now available to both of them. This API will be stripped of the device arguments so that it only cares about hotplugging. * Structures embodying pci and vdev devices are going to be reworked to integrate new common rte_device / rte_driver objects (see http://dpdk.org/ml/archives/dev/2016-January/031390.html). ethdev and crypto libraries will then only handle those objects so that they do not need to care about the kind of devices that are being used, making it easier to add new buses later. * 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 will change for rte_mempool struct to move the cache-related fields to the more appropriate rte_mempool_cache struct. The mempool API is also changed to enable external cache management that is not tied to EAL threads. Some mempool get and put calls are removed in favor of a more compact API. The ones that remain are backwards compatible and use the per-lcore default cache if available. This change targets release 16.07. * 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 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 in 16.07 and will be removed in 16.11.
