Well, the switch does not sense carrier on the corresponding port while the laptop is suspended, so I'm pretty sure nothing gets delivered over that link. No, I suspect the ACPI suspend method turns off the RTL8208 PHY chip, maybe as a side effect... But I don't need working WoL on this system - look, this is cheap old stuff that the previous owner considered electronic waste. I even suspect this was because wired network never worked well after resume. With your fix, this piece can still serve some purpose. Thank you! Petr T
