Hi Andrew,

Thank you for reviewing the patches.

I think I misstated it here. I meant that the higher-layer drivers are 
the OATC14 10Base-T1S PHY drivers, which can use the generic APIs 
implemented in PHYLIB to obtain SQI value. Currently, this patch series 
is intended only for ethtool.

I should have described the patch series more specifically as follows:

This patch series adds Signal Quality Indicator (SQI) and enhanced SQI+ 
support for OATC14 10Base-T1S PHYs, along with integration into the 
Microchip T1S PHY driver. This enables ethtool to report the SQI value 
for OATC14 10Base-T1S PHYs.

If this explanation clarifies things, I will update it in the next version.

Best regards,
