-* The ethdev structures rte_eth_link, rte_eth_dev_info and rte_eth_conf
- must be updated to support 100G link and to have a cleaner link speed API.
-
* ABI changes are planned for adding four new flow types. This impacts
RTE_ETH_FLOW_MAX. The release 2.2 does not contain these ABI changes,
but release 2.3 will. [postponed]
The structure ``rte_eth_dev_info`` has now a ``speed_capa`` bitmap, which
allows the application to know the supported speeds of each device.
+* **Added bitmap of link speeds to advertise.**
+
+ Allow defining a set of advertised speeds for auto-negotiation,
+ explicitly disabling link auto-negotiation (single speed)
+ and full auto-negotiation.
+
* **Added new poll-mode driver for Amazon Elastic Network Adapters (ENA).**
The driver operates variety of ENA adapters through feature negotiation
* The ethdev structure ``rte_eth_dev_info`` was changed to support device
speed capabilities.
+* The ethdev structures ``rte_eth_link`` and ``rte_eth_conf`` were changed to
+ support the new link API.
+
* The functions ``rte_eth_dev_udp_tunnel_add`` and ``rte_eth_dev_udp_tunnel_delete``
have been renamed into ``rte_eth_dev_udp_tunnel_port_add`` and
``rte_eth_dev_udp_tunnel_port_delete``.
