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.
