Hi Ninad,

Thanks. When are you planning to push this change? I might need to hold on to
mac changes until then.

Yes. We have a plan to push the patch about RGMII delay configuration.
Currently, I try to align our SDK to kernel.

Thanks. What will be the "phy-mode" value after you make these changes?

Will it be "rgmii-id" for MAC1..4?

It should be.

If that is the case then I can test it with current configuration which may
add extra delays in the RX from PHY side.

I would then expect traffic will not flow correctly, and your see CRC
errors, because of double delays. It is however a useful test, because
if it does somehow work, it probably means the PHY driver is also
broken with its handling of delays. I don't know what PHY driver you
are using, but those in mainline should be correct, it is something i
try to review carefully.
