This device seems to have switch port 7 connected to the CPU: vlan1ports=1 2 3 5 7* vlan2ports=0 7u it should be handled by eth1 and NVRAM seems to confirm that (no et0macaddr entry, existing et1macaddr & et1phyaddr entries). One of the remaining ports (4/8?) may be connected to the Quantenna SoC. Original firmware boot log contains following messages: (0x00,0x5d)Port 5 States Override: 0xfb (0x00,0x5f)Port 7 States Override: 0xfb (0x00,0x0e)Port 8 States Override: 0x0a (why does it force port 5 state?!)
