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 --387ade367386a6356486f6ee7b635420fbf56ee5ca28a94e7e0254cdeefb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iKgEABMJADAWIQTIVZIcOo5wfU/AngkSJzzuPgIf+AUCaHTVchIcbXdhbGxlQGtl cm5lbC5vcmcACgkQEic87j4CH/hHLwF9E9ztKCoOYS0RHC6gA9ZJQpIMkhGKEO9j 1KseN/0Iehs3rgSim31YE3mtYR6pufKrAX9dE6aY41tiyR4+KV9wg5ozGle9rDLz 8veF90sPBa1PQS56tKbBI4rDvyOKhE7FUtM= =BTle -----END PGP SIGNATURE----- --387ade367386a6356486f6ee7b635420fbf56ee5ca28a94e7e0254cdeefb--
