+ - ``rte_eal_mbuf_default_mempool_ops``
+
+* mempool: several API and ABI changes are planned in v18.05.
+ The following functions, introduced for Xen, which is not supported
+ anymore since v17.11, are hard to use, not used anywhere else in DPDK.
+ Therefore they will be deprecated in v18.05 and removed in v18.08:
+
+ - ``rte_mempool_xmem_create``
+ - ``rte_mempool_xmem_size``
+ - ``rte_mempool_xmem_usage``
+
+ The following changes are planned:
+
+ - removal of ``get_capabilities`` mempool ops and related flags.
+ - substitute ``register_memory_area`` with ``populate`` ops.
+ - addition of new ops to customize required memory chunk calculation,
+ customize objects population and allocate contiguous
+ block of objects if underlying driver supports it.
+
+* mbuf: The opaque ``mbuf->hash.sched`` field will be updated to support generic
+ definition in line with the ethdev TM and MTR APIs. Currently, this field
+ is defined in librte_sched in a non-generic way. The new generic format
+ will contain: queue ID, traffic class, color. Field size will not change.
+
+* ethdev: a new Tx and Rx offload API was introduced on 17.11.
+ In the new API, offloads are divided into per-port and per-queue offloads.
+ Offloads are disabled by default and enabled per application request.
+
+ The old ethdev - drivers offload interface will be deprecated on 18.05.
+ This includes:
+ - removal of the conversion in ethdev from new offloading API to old API for drivers.
+
+ In later releases the old offloading API will be deprecated, which will include:
+ - removal of ``ETH_TXQ_FLAGS_NO*`` flags.
+ - removal of ``txq_flags`` field from ``rte_eth_txconf`` struct.
+ - removal of the offloads bit-field from ``rte_eth_rxmode`` struct.
+
+* 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+ HASH and L2_TUNNEL, is superseded by the generic flow API (rte_flow) in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.
+
+* ethdev: A new rss level field planned in 18.05.
+ The new API add rss_level field to ``rte_eth_rss_conf`` to enable a choice
+ of RSS hash calculation on outer or inner header of tunneled packet.
+
+* ethdev: A work is being planned for 18.05 to expose VF port representors
+ as a mean to perform control and data path operation on the different VFs.
+ As VF representor is an ethdev port, new fields are needed in order to map
+ between the VF representor and the VF or the parent PF. Those new fields
+ are to be included in ``rte_eth_dev_info`` struct.
+
+* i40e: The default flexible payload configuration which extracts the first 16
+ bytes of the payload for RSS will be deprecated starting from 18.02. If
+ required the previous behavior can be configured using existing flow
+ director APIs. There is no ABI/API break. This change will just remove a
+ global configuration setting and require explicit configuration.
