Using Microchip KSZ9896 switch

Hi,

I am trying to use KSZ9896 on my custom board which is using Xavier AGX som.KSZ9896 connected over RGMII interface on port 6 and I2C bus. I am trying to use the driver from the below link.

I have this doubt, why do we need to configure the registers using reg_bin utility after installing the driver?
Also have anyone tried implementing this on I2C ?

Thanks
Ashik P.

I remember the issue behind this one is not what we can resolve. The steps are suggested by the vendor of KSZ9896.
