Hi Ti,

We are using Linux RT SDK 07.01.00.18 on our evm board.

Our goal is to rename the ethernet port name.

For example, rename the eth2 to eth3, and rename eth3 to th2.

We can do this by using ioctl with SIOCSIFNAME via socket from user space.

However, we still want to know is there any possible to achieve this by using shell script?

I have tried to use "ip link set eth2 name eth3" command, but always got "RTNETLINK answers: File exists" .

Thanks.

Hi Eric,

I am not aware of any command line methods for this. This is done statically via DT config in TI devices. I think you will find some options of doing this via udev on linux forums but I cannot guarantee that it will work on AM65.

I guess if you can do it via IOCTL then stick to it if it's not blocking you.
