+* 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: The ``struct rte_flow_item_eth`` and ``struct rte_flow_item_vlan``
+ structs will be modified, to include an additional value, indicating existence
+ or absence of a VLAN header following the current header, as proposed in RFC
+ https://mails.dpdk.org/archives/dev/2020-August/177536.html.
+
+* ethdev: The ``struct rte_flow_item_ipv6`` struct will be modified to include
+ additional values, indicating existence or absence of IPv6 extension headers
+ following the IPv6 header, as proposed in RFC
+ https://mails.dpdk.org/archives/dev/2020-August/177257.html.
+
+* vhost: Vhost-user dequeue zero-copy support will be removed in 20.11.
+ The only known user is OVS where the feature is still experimental,
+ and has not received any update for 2.5 years.
+ This feature faces reliability issues and is often conflicting with
+ new features being implemented.
+
+* security: The API ``rte_security_session_create`` takes only single mempool
+ for session and session private data. So the application need to create
+ mempool for twice the number of sessions needed and will also lead to
+ wastage of memory as session private data need more memory compared to session.
+ Hence the API will be modified to take two mempool pointers - one for session
+ and one for private data.
+
+* cryptodev: ``RTE_CRYPTO_AEAD_LIST_END`` from ``enum rte_crypto_aead_algorithm``,
+ ``RTE_CRYPTO_CIPHER_LIST_END`` from ``enum rte_crypto_cipher_algorithm`` and
+ ``RTE_CRYPTO_AUTH_LIST_END`` from ``enum rte_crypto_auth_algorithm``
+ will be removed.
