i.MX6 MDIO turn around

I am working on a design hooking up an i.MX6Q to an ethernet chip that has an errata on it's MDIO interface where the chip does not drive the MDIO line low correctly during a turn around cycle.  Does the i.MX6 check the state of the bus during a turn around cycle or just report back the data?

This question is similar to one asked in the Qoriq forum "QorIQ EMI_MDIO controller ACK bit checking"

Hi Andrew

i.MX6Q does not check the state of the bus during a turn around cycle
and have not bit similar to MDIO_CFG[MDIO_RD_ER] as some
mentioned QorIQ processors.

Best regards
