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?
