Hi Biser,
Our customer is using their original ethernet driver without the TCP/IP stack in the loopback test. All ports are set to Normal priority mode (Px_TX_IN_CTL.TX_IN_SEL). Should the Dual MAC mode be used?
I checked the following posts.

Enabling ALE_BYPASS was not effective.
Are there any other configurations that should be examined?
Best regards,
