Hi Jiri ds = dsa_switch_alloc(&mdiodev->dev, DSA_MAX_PORTS); It is allocating a switch with 12 ports. However only 4 of them have names. So the core only creates slave devices for those 4. This is a useful test. Real hardware often has unused ports. A WiFi AP with a 7 port switch which only uses 6 ports is often seen. Andrew
