* eal: The function ``rte_eal_remote_launch`` will return new error codes
after read or write error on the pipe, instead of calling ``rte_panic``.
+* eal: The lcore state ``FINISHED`` will be removed from
+ the ``enum rte_lcore_state_t``.
+ The lcore state ``WAIT`` is enough to represent the same state.
+
* eal: Making ``struct rte_intr_handle`` internal to avoid any ABI breakages
in future.
The second union is for existing ``fragment_offset``
and new bitfield for fragment flags and offset.
+* vhost: The experimental tags of ``rte_vhost_driver_get_protocol_features``,
+ ``rte_vhost_driver_get_queue_num``, ``rte_vhost_crypto_create``,
+ ``rte_vhost_crypto_free``, ``rte_vhost_crypto_fetch_requests``,
+ ``rte_vhost_crypto_finalize_requests``, ``rte_vhost_crypto_set_zero_copy``,
+ ``rte_vhost_va_from_guest_pa``, ``rte_vhost_extern_callback_register``,
+ and ``rte_vhost_driver_set_protocol_features`` functions will be removed
+ and the API functions will be made stable in DPDK 21.11.
+
* compressdev: ``min`` and ``max`` fields of ``rte_param_log2_range`` structure
will be renamed in DPDK 21.11 to avoid conflict with Windows Sockets headers.
has a limited size ``uint16_t``.
It will be moved and extended as ``uint32_t`` in DPDK 21.11.
+* cryptodev: The structure ``rte_crypto_sym_vec`` would be updated to add
+ ``dest_sgl`` to support out of place processing.
+ This field will be null for inplace processing.
+ This change is targeted for DPDK 21.11.
+
+* cryptodev: The structure ``rte_crypto_vec`` would be updated to add
+ ``tot_len`` to support total buffer length.
+ This is required for security cases like IPsec and PDCP encryption offload
+ to know how much additional memory space is available in buffer other than
+ data length so that driver/HW can write expanded size data after encryption.
+ This change is targeted for DPDK 21.11.
+
* cryptodev: The interface between library and drivers will be marked
as internal in DPDK 21.11.
+* security: Hide structure ``rte_security_session`` and expose an opaque
+ pointer for the private data to the application which can be attached
+ to the packet while enqueuing.
+
+* security: The IPsec configuration structure
+ ``struct rte_security_ipsec_xform`` will be updated with new members to allow
+ SA lifetime configuration. A new structure would be introduced to replace the
+ current member, ``esn_soft_limit``.
+
+* security: The IPsec SA config options ``struct rte_security_ipsec_sa_options``
+ will be updated with new fields to support new features like IPsec inner
+ checksum, tunnel header verification, TSO in case of protocol offload.
+
+* eventdev: The file ``rte_eventdev_pmd.h`` will be renamed to ``eventdev_driver.h``
+ to make the driver interface as internal and the structures ``rte_eventdev_data``,
+ ``rte_eventdev`` and ``rte_eventdevs`` will be moved to a new file named
+ ``rte_eventdev_core.h`` in DPDK 21.11.
+ The ``rte_`` prefix for internal structures and functions will be removed across the
+ library.
+ The experimental eventdev trace APIs and ``rte_event_vector_pool_create``,
+ ``rte_event_eth_rx_adapter_vector_limits_get`` will be promoted to stable.
+ An 8-byte reserved field will be added to the structure ``rte_event_timer`` to
+ support future extensions.
+
* eventdev: The structure ``rte_event_eth_rx_adapter_queue_conf`` will be
extended to include ``rte_event_eth_rx_adapter_event_vector_config`` elements
and the function ``rte_event_eth_rx_adapter_queue_event_vector_config`` will
values to the function ``rte_event_eth_rx_adapter_queue_add`` using
the structure ``rte_event_eth_rx_adapter_queue_add``.
+* eventdev: Reserved bytes of ``rte_event_crypto_request`` is a space holder
+ for ``response_info``. Both should be decoupled for better clarity.
+ New space for ``response_info`` can be made by changing
+ ``rte_event_crypto_metadata`` type to structure from union.
+ This change is targeted for DPDK 21.11.
+
* metrics: The function ``rte_metrics_init`` will have a non-void return
in order to notify errors instead of calling ``rte_exit``.
* security: The functions ``rte_security_set_pkt_metadata`` and
``rte_security_get_userdata`` will be made inline functions and additional
flags will be added in structure ``rte_security_ctx`` in DPDK 21.11.
+
+* cryptodev: The structure ``rte_crypto_op`` would be updated to reduce
+ reserved bytes to 2 (from 3), and use 1 byte to indicate warnings and other
+ information from the crypto/security operation. This field will be used to
+ communicate events such as soft expiry with IPsec in lookaside mode.
