Although Zyxel's marketing materials call this a "series," the EX3510-B1 appears to be a very minor revision of the EX3510-B0, with only changes that are transparent to software. As far as Linux is concerned, this "series" effectively represents a single model.

WiFi support consists of a BCM6710 and a BCM6715 attached to separate PCIe buses. Add an initial devicetree for this system, with support for: - Onboard UART (per base dtsi) - USB (2.0 only; superspeed devices are treated as high-speed due to an unknown cause) - Both buttons (rear reset, front WPS) - Almost all LEDs: - Power (red/green) - Internet (red/green) - WAN (green) - LAN (green; anode is connected to GPIO 13 so currently nonfunctioning) - USB (green) - WPS button (red/green) - Absent in DT: There are 2.4GHz/5.0GHz WiFi status LEDs connected to the WiFi chips instead of the SoC. - NAND flash - Embedded Ethernet switch - Factory-programmed Ethernet MAC address WiFi cannot be enabled at this time due to Linux lacking drivers for both the PCIe controllers and the PCIe WiFi peripherals.
