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