Last modified: 2013-04-09 06:23:26 UTC

sky2: pci power savings
Turn on special bits to save more power when device is shutdown.
Tested on a limited range of hardware, some of the bits are for
hardware that probably isn't even in production (like Yukon Supreme)
and was ported from the vendor driver.
