Intel I219-LM reports link up -> link down -> link up after hot-plugging
the Ethernet cable.
Please could you quote some parts of 802.3 which state this is a
problem. How is this breaking the standard.

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.
