2 =======================
4 See the :doc:`guidelines document for details of the ABI policy </contributing/versioning>`.
5 API and ABI deprecation notices are to be posted here.
11 * The EAL function pci_config_space_set is deprecated in release 16.04
12 and will be removed from 16.07.
13 Macros CONFIG_RTE_PCI_CONFIG, CONFIG_RTE_PCI_EXTENDED_TAG and
14 CONFIG_RTE_PCI_MAX_READ_REQUEST_SIZE will be removed.
15 The /sys entries extended_tag and max_read_request_size created by igb_uio
18 * The following fields have been deprecated in rte_eth_stats:
19 ibadcrc, ibadlen, imcasts, fdirmatch, fdirmiss,
20 tx_pause_xon, rx_pause_xon, tx_pause_xoff, rx_pause_xoff
22 * ABI changes are planned for adding four new flow types. This impacts
23 RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
24 but release 2.3 will. [postponed]
26 * ABI change is planned for the rte_mempool structure to allow mempool
27 cache support to be dynamic depending on the mempool being created
28 needing cache support. Saves about 1.5M of memory per rte_mempool structure
29 by removing the per lcore cache memory. Change will occur in DPDK 16.07
30 release and will skip the define RTE_NEXT_ABI in DPDK 16.04 release. The
31 code affected is app/test/test_mempool.c and librte_mempool/rte_mempool.[ch].
32 The rte_mempool.local_cache will be converted from an array to a pointer to
33 allow for dynamic allocation of the per lcore cache memory.
