2. Set adv_1000autoneg_cap to 0.
Setting Parameters Using the ge.conf File
Youcan also specify the properties described in this section on a per-device basis by
creating a ge.conf file in the /kernel/drv directory.Use a ge.conf file when
you need to set a particular parameter for a device in the system. The parameters
you set are read and write parameters that are listed in “Driver Parameter Values
and Definitions” on page 5.
The man pages for prtconf (1M) and driver.conf (4) include additional
details.

Understanding the ge.conf File

Obtain the hardware path names for the ge devices in the device tree.
Typicallythe path names and the associated instance numbers will be present in the
/etc/path_to_inst file.
where:
“/sbus@b,0/network@2,100000” specifies the hardware node name in the
device tree.
“0” is the instance number.
“ge” is the driver name.
In the device path name, the last component after the last /character and before
the @character (network) is the device name.
The path name before the last component (sbus@b,0) is the parent name.
For Sun GigabitEthernet/S:
Toidentify an SBus device unambiguously in the ge.conf file, use the name and
parent name of the device. Refer to the sbus(4) man page for more information
about the SBus device specification.
In the previous example:
Name = SUNW,sbus-gem
Class = “sbus”
#grep ge /etc/path_to_inst
“/sbus@b,0/network@2,100000” 0 “ge”
