   Flow API support has been added to CXGBE Poll Mode Driver to offload
   flows to Chelsio T5/T6 NICs.
 
+* **Added eal device event process helper in ethdev.**
+
+  Implement a couple of eal device event handler install/uninstall APIs in
+  ethdev, these helper could let PMDs have chance to manage the eal device
+  event, such as register device event callback, then monitor and process
+  hotplug event.
+
+  * ``rte_eth_dev_event_handler_install`` for PMDs use to install the device
+    event handler.
+  * ``rte_eth_dev_event_handler_uninstall`` for PMDs use to uninstall the device
+    event handler.
