We have rgmii-id in our devicetree which is now modified to be just rgmii-rxid. The board has a TI AM67A (J722S) with a Broadcom BCM54210E PHY. I'm not sure, if AM67A MAC doesn't add any delay or if it's too small. I'll need to ask around if there are any measurements but my colleague doing the measurements is on holiday at the moment. -michael
