Hello,
This patch handles the phy reset pin's polarity. AMD8111's PHY_RESET pin is active high by default, but some PHY requires active low reset signal. On mainboards which use 8111's PHY_RESET pin to reset PHY the bios must select the correct PHY_RST_POL for 8111, otherwise the PHY chip would always be held in reset state and can't be accessed by software.
I sent a similar patch several months ago but no response on this list, would someone who has cvs commit right check and apply it?
