 Overview
 ********
 
+Ethernet management API provides functions to manage the Ethernet
+network interface low level status. The caller of these functions can:
+
+* raise ``carrier ON`` or ``carrier OFF`` management events
+* raise ``VLAN enabled`` or ``VLAN disabled`` management events
+
+Typically the ``carrier OFF`` event would be generated by the Ethernet
+device driver when it notices that the Ethernet cable is disconnected.
+The ``carrier ON`` event would be generated if the Ethernet device driver
+notices that the Ethernet cable is re-connected.
+
+Currently the VLAN events are generated by the Ethernet L2 layer when a
+specific VLAN tag is either enabled or disabled.
+
+The user application can monitor these events if it needs to act
+when the corresponding status changes.
