General Status Register
The General Status register provides some basic status information in the 82559. It is an 8-bit entity
at offset 1Dh of the CSR. This register is only present in the 82559 and is not valid for the 82558 or
82557.

Deep Power Down on Link Down. When this bit is 1, the 82559 may
enter a deep power down state (sub 7 mA) in the D2 and D3 power
states while the link is down. At this state, the 82559 does not maintain
link integrity. It is not supported for point to point connection of two end
stations.
Clockrun Disable. When this bit is 1, the 82559 always requests the PCI
CLK. This mode can be used to overcome potential receive overruns
caused by a very long system CLKRUN latency.
