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:
■ Add the parameter values to the /etc/system file when you want to configure
parameters for all devices in the system.
■ 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.
