nxge
Device Driver Parameters 37
▼
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:
b. Locate the path names and the associated instance numbers in the
/etc/path_to_inst
file.
■
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.
# grep nxge /etc/driver_aliases
nxge "pciex108e,abcd"
# 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"
#
#---------------Link Configuration ----------------------
# The link parameters depend on the type of the card
# and the port.
