PHY ID
Reference
Description:
Only for display purposes not used in software.
[PHY#2][PHY#3]
23
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.
24
Advanced firmware feature (ASF/IPMI/UMP)
Configure
Description:
Advanced firmware feature such as Alert Standard Format (ASF) or IPMI is enabled by this
option.
Enable(1)
If the ASF/IPMI/UMP code is loaded in NVRAM it is loaded and
executed by the device.
Disable(2)
No ASF/IPMI/UMP functionality is provided when disable.
25
Dual MAC mode
Configure
Description:
This option is only valid for a dual port device such as a 5704. The physical ports will be
named MAC_A an MAC_B for the discussion below.
Normal(0)
MAC_A and MAC_B are available and are supported as PCI function 0
& 1.
MAC_B only(1)
MAC_B is available and is supported as PCI function 0. MAC_A is
disable.
21
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

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.
