Code:
apt-get install ethtool net-tools ethstatus ethstats

hi wadhah,

Thanks for ur kind info.

I am using embedded router. So I dont want install those tools. Actualy I am giving some ioctls to find the speed of the
device,I am getting zero. So I verified in the sysfs on router and observed that speed file is not get create.

So I am expecting in the drivers point of view ,whose is the responsible to create that file.


Thanks,
Harinath

Hi,
you can adjust the speed with the commande ifconfig with the option speed

Code:
ifconfig eth0 1.1.1.1 .... speed ...
but with an embedded system you can verify if this possible with the commande

Code:
ifconfig --help

Hi All,


I should write a ioctl command,that can get the speeed of the ethernet link. I am using broadcom ehernet driver.
So please tell me how I can read the speed in driver and I can update the useraddress at ioctl cmd.


Thanks,
Harinath
