   In 20.08, explicit deprecation warnings will be displayed when running
   scripts with Python 2.
-* eventdev: Three public data structures will be updated in 20.11;
-  ``rte_event_dev_info``, ``rte_event_dev_config``, and
-  ``rte_event_port_conf``.
-  Two new members will be added to the ``rte_event_dev_info`` struct.
-  The first, max_event_port_links, will be a uint8_t, and represents the
-  maximum number of queues that can be linked to a single event port by
-  this device. The second, max_single_link_event_port_queue_pairs, will be a
-  uint8_t, and represents the maximum number of event ports and queues that
-  are optimized for (and only capable of) single-link configurations
-  supported by this device. These ports and queues are not accounted for in
-  max_event_ports or max_event_queues.
-  One new member will be added to the ``rte_event_dev_config`` struct. The
-  nb_single_link_event_port_queues member will be a uint8_t, and will
-  represent the number of event ports and queues that will be singly-linked
-  to each other. These are a subset of the overall event ports and queues.
-  This value cannot exceed nb_event_ports or nb_event_queues. If the
-  device has ports and queues that are optimized for single-link usage, this
-  field is a hint for how many to allocate; otherwise, regular event ports and
-  queues can be used.
-  Finally, the ``rte_event_port_conf`` struct will be
-  modified as follows. The uint8_t implicit_release_disabled field
-  will be replaced by a uint32_t event_port_cfg field. The new field will
-  initially have two bits assigned. RTE_EVENT_PORT_CFG_DISABLE_IMPL_REL
-  will have the same meaning as implicit_release_disabled. The second bit,
-  RTE_EVENT_PORT_CFG_SINGLE_LINK will be set if the event port links only
-  to a single event queue.
+* eventdev: ABI change to support DLB PMD and future extensions
+  The following structures and will be modified to support to DLB PMD and future
+  extension in the eventdev library.
+  - ``rte_event_dev_info``
+  - ``rte_event_dev_config``
+  - ``rte_event_port_conf``
+  Patches containing justification, documentation, and proposed modifications
