Also, make sure to start the actual text at the margin. ======================================================= * eal: The experimental TLS API added in ``rte_thread.h`` has been renamed from ``rte_thread_tls_*`` to ``rte_thread_*`` to avoid naming redundancy and confusion with the transport layer security term. * pci: The value ``PCI_ANY_ID`` is marked as deprecated and can be replaced with ``RTE_PCI_ANY_ID``. * ethdev: Added a ``rte_flow`` pointer parameter to the function ``rte_flow_dev_dump()`` allowing dump for single flow. * cryptodev: The experimental raw data path API for dequeue ``rte_cryptodev_raw_dequeue_burst`` got a new parameter ``max_nb_to_dequeue`` to provide flexible control on dequeue. * ethdev: The experimental flow API for shared action has been generalized as a flow action handle used in rules through an indirect action. The functions ``rte_flow_shared_action_*`` manipulating the action object are replaced with ``rte_flow_action_handle_*``. The action ``RTE_FLOW_ACTION_TYPE_SHARED`` is deprecated and can be replaced with ``RTE_FLOW_ACTION_TYPE_INDIRECT``. * ethdev: The experimental function ``rte_mtr_policer_actions_update()``, the enum ``rte_mtr_policer_action``, and the struct members ``policer_action_recolor_supported`` and ``policer_action_drop_supported`` have been removed. ABI Changes ----------- .. This section should contain ABI changes. Sample format: * sample: Add a short 1-2 sentence description of the ABI change which was announced in the previous releases and made in this release. Start with a scope label like "ethdev:".
