KSZ8895 - using management interface in SMI mode

Hi,I'm working with a KSZ8895 ethernet switch chip connected to an iMX RT1062 MCU. The switch's bootstraps are configured such that it is in SMI serial interface mode. We can read register values in the restricted MIIM set via the MCU's MDIO interface, but when attempting to read in SMI mode (i.e. t..
