Force PCI Mode
Configure
Description:
PCI bus operational mode configuration.
Enable(1)
When enabled the device uses PCI mode, instead of PCI-X,
independent of the capabilities of the slot the device is plugged into.
Disable(2)
When disabled the device uses the PCI mode of the slot the device is
plugged into; if the device is capable of operating in the required mode.

PHY Type {option no longer supported}
Configure
Description:
PHY line type configuration.
Copper(1)
The communication medium is copper.
Fiber(2)
The communication medium is fiber.
22
PHY ID
Reference
Description:
Only for display purposes not used in software.
[PHY#2][PHY#3]

Max PCI Retry
Configure
Description:
The maximum number of time to retry an aborted PCI operation.
0-7
The number of MAX PCI retries is force by the users configuration.
8=auto
The MAX PCI retry field is selected dynamically by firmware based on
PCI bus type detected.

Led Mode
Configure
Description:
A device can be configured to use one LED to indicate speed and activity or three LEDs.
Use a devices data sheet to verify the LED modes supported by a devices and for
exceptions to the LED modes described below.
Mac Mode (0)
The LEDs are controlled by the value in the Mac LED Control Register.
Phy Mode1 (1)
Three LEDs are used for 10/100/1000 Mbits/s and each is driven
individually by the device.
Phy Mode2 (2)
One LED is used for 10/100/1000 Mbits/s and is connected as described
below.
5700/01 – The Link10 line will indicate link for all speeds. Link100 and
Link1000 will encode the line speed as show in the following table:
Link 100
Link 1000

1000 Mbits/s
For all other 57xx devices the three link lines operate in an open drain
configuration and can be tied together with a pull up resistor to control a
LED.
SharedTraffic
(3)
Mode specific to the 575x and 572x chips. The link LED performs a dual
role: solid when there is a link and blinks when there is activity.
Shasta Mac
Mode (4)
Mode specific to the 575x and 572x chips. The link LED blinks only
when traffic is for Shasta.
Wireless
Combo (5)
Mode specific to the 575x and 572x chips. When link is lost the LEDs
are driven by inputs pins that are connected to the LED signals of a
wireless link.
