Force bge NIC speed

[7280]

Hi,
I want to force NIC speed in 100FD on bge nic.

I know how to do this on eri and qfe, but same commands didn't work for bge.

Example:

ROOT@drfw2 $ ndd -set /dev/eri instance 0
ROOT@drfw2 $ ndd -get /dev/eri link_speed
1
ROOT@drfw2 $ ndd -get /dev/eri link_mode
1

on bge:
ROOT@drfw3 $ ndd -set /dev/bge instance 0
operation failed: Invalid argument
ROOT@drfw3 $ ndd /dev/bge \?
operation failed: Invalid argument
ROOT@drfw3 $ ls -las /dev/bge
2 lrwxrwxrwx 1 root root 29 Sep 27 11:45 /dev/bge -> ../devices/pseudo/clone@0:bge

Any idea?
Thanks,
Tarek

echo "Changing bge0 to 100MB/FD"
ndd -set /dev/bge0 adv_10hdx_cap 0
ndd -set /dev/bge0 adv_10fdx_cap 0
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1

ndd -set /dev/bge0 adv_1000fdx_cap 0
ndd -set /dev/bge0 adv_autoneg_cap 0

echo "Changing bge1 to 1000MB/FD"
ndd -set /dev/bge1 adv_10hdx_cap 0
ndd -set /dev/bge1 adv_10fdx_cap 0
ndd -set /dev/bge1 adv_100hdx_cap 0
ndd -set /dev/bge1 adv_100fdx_cap 0
ndd -set /dev/bge1 adv_1000hdx_cap 0
ndd -set /dev/bge1 adv_1000fdx_cap 1
ndd -set /dev/bge1 adv_autoneg_cap 0

In order to do this you will need to modifiy the bge.conf file. This is a specific driver file for the bge interfaces.

/platform/sun4u/kernel/drv/bge.conf

Good Luck.

Here is some additional info for this configuaration.

# cat /platform/sun4u//kernel/drv/xxx.conf (for ce or bge)The single line entries for each network instance (e.g. ce) for 1000Mbps and 100Mbps speeds should look like these respectively:

**each group beginning "name" has to be one continuous line.

name=”ce” parent=”<physical device path>” unit-address=”<unit-address>” adv_autoneg_cap=1 adv_1000fdx_cap=1 adv_1000hdx_cap=0 adv_100fdx_cap=0 adv_100hdx_cap=0 adv_10fdx_cap=0 adv_10hdx_cap=0 adv_100T4_cap=0;

name=”ce” parent=”<physical device path>” unit-address=”<unit-address>” adv_autoneg_cap=0 adv_1000fdx_cap=0 adv_1000hdx_cap=0 adv_100fdx_cap=1 adv_100hdx_cap=0 adv_10fdx_cap=0 adv_10hdx_cap=0 adv_100T4_cap=0;
