These values should not be zero.  Quite litterally, the hardware
has disappeared out from under the driver.  This could be caused
by either a hardware or driver problem.

But about all I have to say is that my
re0 at pci3 dev 0 function 0: RealTek 8100E/8101E/8102E/8102EL PCIe 
10/100BaseTX (rev. 0x01)
hasn't given me noticable trobule.
