This is not directly LWIP related but I was wondering if there was a way to detect when cable is unplugged through a GMII/RMII interface?
Specifically my hardware does not have the carrier sense pin connected to microcontroller and I was wondering if there was a way to poll the GMII/RMII registers to see when a cable is connected or not?
I did not see anything in the documentation right off but thought I would ask, as maybe I am not looking at the correct registers.
Thanks
