■

The path name before the last component is the parent name.

■

The number after the final

character within quotes is the unit-address.

To identify a PCI device unambiguously in the

ce.conf

file, use the name, parent

name, and the unit-address for the device. Refer to the

pci

(4) man page for more

information about the PCI device specification.

In this example:

■

parent

"/pci@8,600000"

■

unit-address

"1"

2. Set the parameters for the above devices in the

/platform/sun4u/kernel/drv/ce.conf

file.

In the following example, the

adv_autoneg_cap

and

adv_1000fdx_cap

parameters are set for all Sun GigaSwift Ethernet devices. See the

driver.conf(4)

man page for more information.

In the following example, the

adv-autoneg-cap

and

adv-1000fdx-cap

parameters are set for a single instance of the Sun GigaSwift Ethernet device.

Note –

If you omit the

name=

parent=

, and

unit-address=

definitions, the

settings become global to all Sun GigaSwift Ethernet instances.

3. Save the

ce.conf

file.

Usability Enhancements to the Driver

In older Ethernet device drivers, determining the link status for a driver required a
two-step process:

First, you had to set the instance:

adv-autoneg-cap=0 adv-1000fdx-cap=0;

name="pci100b,35" parent="/pci@8,600000" unit-address="1"

adv-autoneg-cap=0 adv-100hdx-cap=0 adv-100fdx-cap=1 adv-1000fdx-cap=0 adv-

10hdx-cap=0 adv-10fdx-cap=0 adv-1000hdx-cap=0 adv-100T4-cap=0;
