Thanks Andrew — and thanks Jacky for the earlier steer too.

We're already on this path. I have a local branch with both U-Boot and
kernel dts switched to phy-mode = "rgmii-id", and the &scu
mac0-clk-delay block removed from the U-Boot dts.

We'll validate end-to-end on hardware first, then send the patches.
I'll make sure the commit messages on both the U-Boot and kernel sides
clearly note that the bootloader has been modified to stop enabling
the MAC delays, so reviewers see the relationship between the two.

Appreciated — but unfortunately tight timelines on our side mean I
can't take on the smarter MAC driver work right now. I'll keep it on
my radar as a follow-up if bandwidth allows.

Thanks again,
Ender
