Here's some general info about the QCA8334 chip that might help. If
you have specific questions let me know and I will try to find

The four ports of the Gigabit switch engine are:
Port 2 and 3 GMAC: 2 *10/100/1000BASE-T
Port 6 GMAC: SerDes/SGMII

It can be configured using serial EEPROM and/or the MDC/MDIO interface.
