If you look further down in
<http://sourceforge.net/tracker/index.php?func=detail&aid=3170405&group_id=42302&atid=447449>
you'll see that I tested that, and it doesn't work :( even if it did
work, it shouldn't be needed: the driver attempts to turn off PCIe ASPM
on affected NICs, and fails, apparently because *something* turns it
back on again.
