Subject: wilc1000 MAC address is 00:00:00:00:00:00

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?
