Hello,

probably my question is stupid, but I'm not an expert! I'm sorry for this!
I'm developing some software on a development board based on AT91SAM9260 processor. I need to power off the ethernet device, but I need a “low level” command. I mean that an “ifconfig eth0 down” command is not suffice to my purpose, I need a command to emulate a cable disconnection, something to power off the yellow LED on the ethernet port.
Maybe I have to implement a function that uses some kernel functions, but I don't know where to start.
Could you please give me a suggestion?
Thanks in advance,

Nicola.
