Chapter 4 Configuring Driver Parameters 53
■unit-address =“0”
In the third line in the previous example:
■parent =“pci@5”
■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 – The difference between setting parameters for all Sun GigaSwift Ethernet
devices and setting parameters for a single instance of the device depends on
whether you include the name=,parent=, and unit-address=. If you omit these
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="pci108e,abba" parent="pci@9,600000" unit-address="2"
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;
#ndd -set /dev/hme instance 2
