How to set up the net connection

[78748547]

@MAVProxyUser Hello, when I tried to control my real robot GO1 PRO with unitree_ros_to_real package, I followed the steps in the readme document. It asked me to find my port name and modify it in the ipconfig.sh file. Here I have two questions:

1. I use the unitree_ros_to_real Packages Version: v3.8.0, but there is no ipconfig.sh file in it. I copied the ipconfig.sh file in Packages Version: v3.5.1 to the unitree_legged_real folder. I want to ask if this is OK and if the contents need to be modified.
2. I don't know where the content in ipconfig.sh needs to be modified. Could you give me an example? Thank you very much.
