Did Xavier MAC support switch between upstream and downstream?

We use Xavier MAC+realtek PHY for ethernet use case, want know did this support switch between upstream and downstream, thanks

Not very sure about your problem.

Could you elaborate it?

Hi Wayne:
In some case,we want control the ethernet only support upstream or downstream , thanks


I am not sure. Have you ever tried this on other platforms? For example, is this feasible on x86 PC? If so, I want to know what kind of tool or driver code that can achieve this.

Hi Wayne:
thanks, hasn’t been tried yet, worried that will need driver support.
