Removed Items
-------------
``RTE_LCORE_FOREACH_SLAVE`` is replaced with
``RTE_LCORE_FOREACH_WORKER``.
+* eal: The definitions related to including and excluding devices
+ has been changed from blacklist/whitelist to block/allow list.
+ There are compatibility macros and command line mapping to accept
+ the old values but applications and scripts are strongly encouraged
+ to migrate to the new names.
+
* eal: The ``rte_logs`` struct and global symbol was made private
and is no longer part of the API.
the structures ``rte_mbuf`` and ``rte_mbuf_ext_shared_info``.
The field ``refcnt`` is remaining from the old unions.
+* mbuf: Removed the unioned fields ``userdata`` and ``udata64``
+ from the structure ``rte_mbuf``. It is replaced with dynamic fields.
+
+* mbuf: Removed the field ``seqn`` from the structure ``rte_mbuf``.
+ It is replaced with dynamic fields.
+
+* mbuf: Removed the field ``timestamp`` from the structure ``rte_mbuf``.
+ It is replaced with the dynamic field RTE_MBUF_DYNFIELD_TIMESTAMP_NAME
+ which was previously used only for Tx.
+
* pci: Removed the ``rte_kernel_driver`` enum defined in rte_dev.h and
replaced with a private enum in the PCI subsystem.
As the data of ``uint8_t`` will be truncated when queue number under
a TC is greater than 256.
+* ethdev: Removed the legacy filter API, including
+ ``rte_eth_dev_filter_supported()`` and ``rte_eth_dev_filter_ctrl()``.
+
+* ethdev: Removed the legacy L2 tunnel configuration API, including
+ ``rte_eth_dev_l2_tunnel_eth_type_conf()`` and
+ ``rte_eth_dev_l2_tunnel_offload_set()``..
+
* vhost: Moved vDPA APIs from experimental to stable.
* vhost: Add a new function ``rte_vhost_crypto_driver_start`` to be called
* bpf: ``RTE_BPF_XTYPE_NUM`` has been dropped from ``rte_bpf_xtype``.
+* gso: Changed ``rte_gso_segment`` behaviour and return value:
+
+ * ``pkt`` is not saved to ``pkts_out[0]`` if not GSOed.
+ * Return 0 instead of 1 for the above case.
+ * ``pkt`` is not freed, no matter whether it is GSOed, leaving to the caller.
+
* acl: ``RTE_ACL_CLASSIFY_NUM`` enum value has been removed.
This enum value was not used inside DPDK, while it prevented to add new
classify algorithms without causing an ABI breakage.
