Dear Team,
We have to enable SFP10G & SFP1G connection for our product.
Here are all the configs we applied, the SFP 10G link up with a good eye diagram. However, the SFP 1G link up failed.
Could you provide any comments?

Enable Raw data could get both 1G and 10G link up. Clear bit[5] of 0x9 and clear bit[7:5] of 0x1e.
Why does the link fail with retimed data? Please help to clarify this case.
