[Mrutyunjay]

hi,
need interface to know status of Link 
in OS based LwIP 1.3.2 !

1. is Ethernet cable connected(hub/switch).
2. What is Link speed is connected at
   a. 10mbps/100mbps. 
   b. full-duplex or half duplex.
3. how to enable or disable Auto-Negotiations.

Because I have uC(TI LM3S6911) with on chip PHY/MAC supports 10/100 option .
customer is insisting on connection to their network on 100 mbps Full duplex only else sound warning on device.
