If the link partner is capable of auto-negotiation (when

lp_autoneg_cap

is 1) then

the speed and mode information is displayed when you use auto-negotiation and get
the link partner capabilities.

Setting

qfe

Driver Parameters

You can set the

qfe

device driver parameters in three ways (

ndd

,

/etc/system

,

and

qfe.conf

), depending on your needs. To set parameters that are valid until you

reboot the system, use the

ndd

utility. Using

ndd

is a good way to test parameter

settings.

To set parameters so they remain in effect after you reboot the system:

4

Add the parameter values to the

/etc/system

file when you want to configure

parameters for all devices in the system.

4

Create a

/kernel/drv/qfe.conf

file and add parameter values to the this file

when you need to set a particular parameter for a device in the system.

Setting Parameters Using the

ndd

Utility

Use the

ndd

utility to configure parameters that are valid until you reboot the

system. The

ndd

utility supports any networking driver, which implements the Data

Link Provider Interface (DLPI).

The following sections describe how you can use the

qfe

driver and the

ndd

utility

to modify (with the

-set

option) or display (without the

-set

option) the

parameters for each

SUNW,qfe

device.

Identifying Device Instances

Before you use the

ndd

utility to get or set a parameter for a

qfe

device, you must

specify the device instance for the utility since there will be at least four

SUNW,qfe

devices.

To Specify the Device Instance for the

ndd

Utility

1. Check the

/etc/path_to_inst

file to identify the instance associated with a

particular device.

# grep qfe /etc/path_to_inst

"/pci@1f,2000/pci@2/SUNW,qfe@0,1" 4 "qfe"
