Removed Items
-------------
Also, make sure to start the actual text at the margin.
=======================================================
+* eal: The lcore state ``FINISHED`` is removed from
+ the ``enum rte_lcore_state_t``.
+ The lcore state ``WAIT`` is enough to represent the same state.
+
+* eal: Made ``rte_intr_handle`` structure definition hidden.
+
* kvargs: The experimental function ``rte_kvargs_strcmp()`` has been
removed. Its usages have been replaced by a new function
``rte_kvargs_get_with_value()``.
* mempool: The mempool API macros ``MEMPOOL_PG_*`` are deprecated and
will be removed in DPDK 22.11.
+* mbuf: The mbuf offload flags ``PKT_*`` are renamed as ``RTE_MBUF_F_*``. A
+ compatibility layer will be kept until DPDK 22.11.
* net: Renamed ``s_addr`` and ``d_addr`` fields of ``rte_ether_hdr`` structure
to ``src_addr`` and ``dst_addr``, respectively.
should be provided, and offset for immediate source bitfield is assigned
from destination one.
+* vhost: ``rte_vdpa_register_device``, ``rte_vdpa_unregister_device``,
+ ``rte_vhost_host_notifier_ctrl`` and ``rte_vdpa_relay_vring_used`` vDPA
+ driver interface are marked as internal.
+
* cryptodev: The API rte_cryptodev_pmd_is_valid_dev is modified to
rte_cryptodev_is_valid_dev as it can be used by the application as
well as PMD to check whether the device is valid or not.
* eventdev: Moved memory used by timer adapters to hugepage. This will prevent
TLB misses if any and aligns to memory structure of other subsystems.
+* fib: Added the ``rib_ext_sz`` field to ``rte_fib_conf`` and ``rte_fib6_conf``
+ so that user can specify the size of the RIB extension inside the FIB.
+
ABI Changes
-----------
Also, make sure to start the actual text at the margin.
=======================================================
+* ethdev: All enums & macros updated to have ``RTE_ETH`` prefix and structures
+ updated to have ``rte_eth`` prefix. DPDK components updated to use new names.
+
* ethdev: Input parameters for ``eth_rx_queue_count_t`` was changed.
Instead of pointer to ``rte_eth_dev`` and queue index, now it accepts pointer
to internal queue data as input parameter. While this change is transparent
to be transparent for both users (no changes in user app is required) and
PMD developers (no changes in PMD is required).
+* vhost: rename ``struct vhost_device_ops`` to ``struct rte_vhost_device_ops``.
+
+* cryptodev: Made ``rte_cryptodev``, ``rte_cryptodev_data`` private
+ structures internal to DPDK. ``rte_cryptodevs`` can't be accessed directly
+ by user any more. While it is an ABI breakage, this change is intended
+ to be transparent for both users (no changes in user app is required) and
+ PMD developers (no changes in PMD is required).
+
* security: ``rte_security_set_pkt_metadata`` and ``rte_security_get_userdata``
routines used by inline outbound and inline inbound security processing were
made inline and enhanced to do simple 64-bit set/get for PMDs that do not
