Driuchatyi Nikolay, I'm not sure what "HW-PHY bug" means precisely. You may want Guo-Fu to clarify what that means (ex. firmware, hardware design flaw, etc.).
One way to double check is test it with Windows. If you get gigabit speeds, then I would think (perhaps naively) it's a bug in the linux driver versus a bug elsewhere.
