Hi, I'm using the WILC1000 wifi and with NetworkManager [1] I see issues in certain situations I see problems. I was able to reduce the problem and have now found out that the cause is that the interface has the HW MAC address is 00:00:00:00:00 after startup. Only when the interface is startup (ip link set dev wlan0 up), the driver sets a "valid" address. Is this a valid behavior and shouldn't the address already be set after loading the driver?
