And then > you could all have working Ethernet.... Hi Andrew, I've already reached out to Ryan and Jacky from ASPEED regarding the topic a few weeks ago. Originally I thought MAC-side clock delay was only needed for fixed-linked (for example, in darwin dts), but looks like it's also impacting platforms with PHY.. Anyways I will follow up with Jacky/Ryan after addressing all the comments for this patch series. Thanks, Tao
