1. This indication is asserted when the 82574 manageability block reloads the NVM and its internal database is updated to the NVM
2. In single-address mode, the 82574 reports the highest power-state modes in both devices. The "D" state is marked in this order:

Status Data Byte 1
Status data byte 2 is used by the MC to indicate whether the LAN device driver is alive
and running.
The LAN device driver valid indication is a bit set by the LAN device driver during
initialization; the bit is cleared when the LAN device driver enters a Dx state or is
cleared by the hardware on a PCI reset.
Bits 2 and 1 indicate that the LAN device driver is stuck. Bit 2 indicates whether the
interrupt line of the LAN function is asserted. Bit 1 indicates whether the LAN device
driver dealt with the interrupt line before the last Read Status cycle.

1b = A TCO command abort event occurred since the last read status cycle.
0b = A TCO command abort event did not occur since the last read status cycle.
0b = LAN link down.
1b = LAN link up.
Contains the value of the PHY_Link_Up bit. When set, indicates that the PHY link is
configured to keep the link up.
