The Raspberry Pi 3 B+ has the following major differences compared to the model 3 B: * Microchip LAN7515 (Gigabit Ethernet with integrated USB 2.0 HUB) * Cypress CYW43455 (802.11n/ac and BT 4.2) We need to add the USB LAN chip so the bootloader can add the MAC address. This is necessary because there ain't an EEPROM or a valid OTP.
