right now the "spec" for Linux network drivers assumes that you put the NIC into D3 on down, except for cases where Wake-on-Lan is enabled etc. > Some chips support more > fine-grained power management, so we could do something more sensible in > that case - but right now, there doesn't seem to be a lot of driver > support for it. sounds like that's the right approach at least .. not talking to the PCI hardware directly from userspace... I can see the point of having more than just "UP" and "DOWN" as interface states; "UP", "DOWN" and "OFF" for example... -- if you want to mail me at work (you don't), use arjan (at) linux.intel.com Test the interaction between Linux and your BIOS via http://www.linuxfirmwarekit.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
