IMHO the patch is ok. If there are not any further comments, I mark your patchset for merging.
- ksz9031_phy_extended_write(phydev, 0x02,
MII_KSZ9031_EXT_RGMII_CLOCK_SKEW,MII_KSZ9031_MOD_DATA_NO_POST_INC, 0x03FF);
I had also some issues with KSZ9031 and i.MX6. Gigabit starts working only after setting the clock skew. I see you set the register again with the default value (0x3FF). Because it is the reset value, it is not required to set it again, but more important : have you make a trying enabling Gb and adjusting only this extended register ? Rather the KSZ9031's manual is not clear and does not say a lot about it,
Best regards, Stefano Babic
