* The log history is deprecated.
It is voided in 16.07 and will be removed in release 16.11.
+* The ethdev library file will be renamed from libethdev.* to librte_ethdev.*
+ in release 16.11 in order to have a more consistent namespace.
+
+* In 16.11 ABI changes are planned: the ``rte_eth_dev`` structure will be
+ extended with new function pointer ``tx_pkt_prep`` allowing verification
+ and processing of packet burst to meet HW specific requirements before
+ transmit. Also new fields will be added to the ``rte_eth_desc_lim`` structure:
+ ``nb_seg_max`` and ``nb_mtu_seg_max`` providing information about number of
+ segments limit to be transmitted by device for TSO/non-TSO packets.
+
* 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
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.
+* ABI changes are planned for 16.11 in the ``rte_mbuf`` structure: some fields
+ may be reordered to facilitate the writing of ``data_off``, ``refcnt``, and
+ ``nb_segs`` in one operation, because some platforms have an overhead if the
+ store address is not naturally aligned. Other mbuf fields, such as the
+ ``port`` field, may be moved or removed as part of this mbuf work.
* 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.
+
+* The APIs rte_mempool_count and rte_mempool_free_count are being deprecated
+ on the basis that they are confusing to use - free_count actually returns
+ the number of allocated entries, not the number of free entries as expected.
+ They are being replaced by rte_mempool_avail_count and
+ rte_mempool_in_use_count respectively.
+
+* The mempool functions for single/multi producer/consumer are deprecated and
+ will be removed in 16.11.
+ It is replaced by rte_mempool_generic_get/put functions.
+
+* The ``rte_ivshmem`` feature (including library and EAL code) will be removed
+ in 16.11 because it has some design issues which are not planned to be fixed.
+
+* The vhost-cuse will be removed in 16.11. Since v2.1, a large majority of
+ development effort has gone to vhost-user, such as multiple-queue, live
+ migration, reconnect etc. Therefore, vhost-user should be used instead.
+
+* Driver names are quite inconsistent among each others and they will be
+ renamed to something more consistent (net and crypto prefixes) in 16.11.
+ Some of these driver names are used publicly, to create virtual devices,
+ so a deprecation notice is necessary.
+
+* API will change for ``rte_port_source_params`` and ``rte_port_sink_params``
+ structures. The member ``file_name`` data type will be changed from
+ ``char *`` to ``const char *``. This change targets release 16.11.
