e1000e: reset MAC-PHY interconnect on 82577/82578 during Sx->S0
During Sx->S0 transitions, the interconnect between the MAC and PHY on
82577/82578 can remain in SMBus mode instead of transitioning to the
PCIe-like mode required during normal operation. Toggling the LANPHYPC
Value bit essentially resets the interconnect forcing it to the correct
mode.
