In the short term, you can always put the port into D3 using setpci (once the driver is unloaded), which will take down the link if wake on is disabled. Linux unfortunately doesn't have good device power management controls yet.
If you would like us to look into this feature as a feature request, we can do so. We haven't had many requests for this particular type of behavior, although we have heard of it. I'm interested in the usage case you have where you need the physical link to go down, because we can't of course do anything about the link state when for instance the machine is first booted, until the driver is loaded.

Hi All, I'm using "Intel(r) 82576 Gigabit Ethernet card" which uses igb driver. I just want to know why we are not able to physically shutdown the interface using the "ifconfig" command? The driver doesn't support it? or the card doesn't support this feature? I was looking in the driver code and the functions "e1000_power_down_phy" is commented out in igb version of the driver. which means???? NOTE: "Wake-on: d" no issue of wake-on. -- Best Regards Masood Mehmood ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
