The MAC address coming from driver might be already used in default
wireless interface. I am not very familiar with wireless devices, maybe
they have pool of MAC addresses we might choose from ...

My point here: we create virtual interface and separate it from other
wireless interfaces => hence we do not need to worry (much) about
concurrency between wireless interfaces. Those interfaces need to have
separate MAC addresses assigned if I understand virtual interfaces concept
right.
