+ The legacy API will be removed in DPDK 20.11.
+
+* ethdev: The flow director API, including ``rte_eth_conf.fdir_conf`` field,
+ and the related structures (``rte_fdir_*`` and ``rte_eth_fdir_*``),
+ will be removed in DPDK 20.11.
+
+* ethdev: The legacy L2 tunnel filtering API is deprecated as the rest of
+ the legacy filtering API.
+ The functions ``rte_eth_dev_l2_tunnel_eth_type_conf`` and
+ ``rte_eth_dev_l2_tunnel_offload_set`` which were not marked as deprecated,
+ will be removed in DPDK 20.11.
+
+* ethdev: New offload flags ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 19.11.
+ This will allow application to enable or disable PMDs from updating
+ ``rte_mbuf::hash::fdir``.
+ This scheme will allow PMDs to avoid writes to ``rte_mbuf`` fields on Rx and
+ thereby improve Rx performance if application wishes do so.
+ In 19.11 PMDs will still update the field even when the offload is not
+ enabled.
+
+* ethdev: ``rx_descriptor_done`` dev_ops and ``rte_eth_rx_descriptor_done``
+ will be removed in 21.11.
+ Existing ``rte_eth_rx_descriptor_status`` and ``rte_eth_tx_descriptor_status``
+ APIs can be used as replacement.
+
+* ethdev: The port mirroring API can be replaced with a more fine grain flow API.
+ The structs ``rte_eth_mirror_conf``, ``rte_eth_vlan_mirror`` and the functions
+ ``rte_eth_mirror_rule_set``, ``rte_eth_mirror_rule_reset`` will be marked
+ as deprecated in DPDK 20.11, along with the associated macros ``ETH_MIRROR_*``.
+ This API will be fully removed in DPDK 21.11.
+
+* ethdev: Queue specific stats fields will be removed from ``struct rte_eth_stats``.
+ Mentioned fields are: ``q_ipackets``, ``q_opackets``, ``q_ibytes``, ``q_obytes``,
+ ``q_errors``.
+ Instead queue stats will be received via xstats API. Current method support
+ will be limited to maximum 256 queues.
+ Also compile time flag ``RTE_ETHDEV_QUEUE_STAT_CNTRS`` will be removed.
+
+* sched: To allow more traffic classes, flexible mapping of pipe queues to
+ traffic classes, and subport level configuration of pipes and queues
+ changes will be made to macros, data structures and API functions defined
+ in "rte_sched.h". These changes are aligned to improvements suggested in the
+ RFC https://mails.dpdk.org/archives/dev/2018-November/120035.html.
