Ethernet Management
Overview
Ethernet management API provides functions to manage the Ethernet network interface low level status. The caller of these functions can:
raise
carrier ON
orcarrier OFF
management eventsraise
VLAN enabled
orVLAN 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.
