▼To Set Driver Parameters Using an nxge.conf File

1.Obtain the hardware path names for the nxge devices in the device tree.

a.Check the /etc/driver_aliases file to identify the name associated with a particular device:

#grep nxge /etc/driver_aliases nxge "pciex108e,abcd"

b.Locate the path names and the associated instance numbers in the

/etc/path_to_inst file.

#grep nxge/etc/path_to_inst "/pci@780/pci@0/pci@8/network@0" 0 "nxge" "/pci@780/pci@0/pci@8/network@0,1" 1 "nxge"

■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 for emphasis).

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

To identify a PCI-E device unambiguously in the nxge.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-E device specification.

In this example:

■	name =	"pciex108e,abcd"
■	parent	= "/pci@780/pci@0/pci@8/network@0"
■	unit-address = "0"
2.	Set the parameters for the nxge devices in the
	/platform/sun4u/kernel/drv/nxge.conf file.
	a. The following parameters can be set using the
	/platform/sun4u/kernel/drv/nxge.conf file.

#---------------	Link Configuration ----------------------

#The link parameters depend on the type of the card

#and the port.
