Thanks for reporting. I don't have these hardware models so I couldn't
verify the issue. After reading the vendor's code I've made attached
patch. I don't know whether it works or not, it's just guess work.
The PHY registers used in the patch are reserved one in my datasheet,
so I don't know what it really does on the hardware.
Btw, according to vendor's driver it seems that there are newer
hardware revisions marked as 8168C and 8168CP. These models seems to
need special handling in PHY area. All datasheet I got shows them as
reserved ones. :-(
