e1000e: 82579 packet drop workaround
In K1 mode (a MAC/PHY interconnect power mode), the 82579 device shuts down the Phase Lock Loop (PLL) of the interconnect to save power. When the PLL starts working, the 82579 device may start to transfer the packet through the interconnect before it is fully functional causing packet drops. This workaround disables shutting down the PLL in K1 mode for 1G link speed.
