Hello, in order to validate the SGMII links of out T1042 design (connected to FPGAs and GbE device) I am looking for a way to loopback the SMGII link on itself (from en external point of view), or better at the MAC level.
That is, incoming traffic received on the RX line of a SGMII is looped back onto the TX.
So far I have not been able to fin any related feature in teh T0140RM or other document.
Is this possible ? Where should I look at ?
