Even further experimentation shows that ethernet functionality can survive the resume for a few minutes before reseting. Once it gets into this state even rmmod/modprobing the r8169 driver won't unwedge the driver.
The symptoms are either the driver detecting an unknown MAC or setting the physical address to 0xfffffffff which is obviously broken. I suspect the hardware has gotten itself wedged somehow.
Is there any way to hard reset the chipset (without power cycling the system)?
