>+* 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.
