Re: [PATCH v3 2/2] ARM: dts: aspeed: Add ASRock Rack B650D4U BMC

Hi Andrew,

Understood. I will not rely only on the vendor DTB value for this.

For the next revision, I will drop rgmii-rxid and use the conservative rgmii
setting unless I can provide board-level evidence that the required RGMII
delay is added by the PCB/PHY configuration.

I am arranging hardware validation for this board, and I will update the
Ethernet node only with evidence from the board/manual/logs.

Thanks,
Prasanth
