In I219-* parts used LSI PHY. This PHY is compliant with the 802.3 IEEE standard if I recall correctly. Auto-negotiation and link establishment are processed following the IEEE standard and could vary from platform to platform but are not violent to the IEEE standard.
En-Wei, My recommendation is not to accept these patches. If you think there is a HW/PHY problem - open a ticket on Intel PAE.
