In this example:
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-jumbo parameter 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-jumbo parameter 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.

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.
