It is kind of a chicken and egg problem for (wireless) networking
drivers. To get IFF_UP from the network layer you have to register a
netdevice. For wireless drivers this means you have to register a wiphy
device with cfg80211 which flags capabilities and optionally are custom
regulatory domain. That information depends on the device and firmware
used. And there we have a full circle.
