How to get the LAN9303 into I2C managed mode

In order to set the LAN9303 into I2C managed mode where you can configure the chip using I2C, strap MNGT1 to 1 and strap MNGT0 to 0. Since the MNGT[1:0] strap pins have an internal pull-up, you only need to strap MNGT0 (pin 26 on the QFN package) to GND using a 10kΩ resistor from this pin to GND.
