We are using i.xm6q based custom board.


We are facing packet loss for size 1k+ consistently.


To debug the issue & verify the driver, I want to enable the loopback as mention in following.

Receive Control Register (ENET_RCR)[LOOP] = 1


But this bit is explained as MII internal loopback, To enable loopback we have to set MII_MODE set to 1 & RMII_MODE set to 0.


Could we use this loopback to test the RGMII driver also?


If not how to test the loopback for RGMII?
