A device can be either a fully functioning device or a kind of reduced functioning device. Let's create a node type member. Drivers will be in charge of setting this value if they handle non-FFD devices, which can be considered the default for now. Provide this information in the interface get netlink command. Create a helper just to check if an rdev is a FFD or not, which will then be useful when bringing scan support.
