Sun Microsystems Ethernet PCI-X Adapter manual Set the parameters for the above devices

Page 44

In this example:

■The first part within the double quotes specifies the hardware node name in the device tree.

■The number not enclosed in quotes is the instance number (shown in bold italics).

■The last part in double quotes is the driver name.

■In the hardware node name, the last component after the last / character and before the @ character is the device name.

■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 ixge.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.

2.Set the parameters for the above devices in the

/platform/sun4u/kernel/drv/ixge.conf file.

In the following example, the accept-jumboparameter is set to enable jumbo frames for all Sun 10-Gigabit Ethernet devices. See the driver.conf(4) man page for more information.

accept-jumbo=1;

In the following example, the accept-jumboparameter is set to enable jumbo frames is set for a single instance of the Sun 10-Gigabit Ethernet device.

In this example:

■parent = "/pci@8,600000"

■unit-address = "0"

name="pci8086,1048.108e.7036" parent="pci@8,600000" unit-address= "0" accept-jumbo=1;

Note – If you omit the name=, parent=, and unit-address=definitions, the settings become global to all Sun 10-Gigabit Ethernet instances.

3. Save the ixge.conf file.
