it's not the order, see below:

It's their names. Currently, the function ..._find_... look at
one level only, while the function ..._has_... does one or more
levels. I think it's better to swap 'has' and 'find' in their names:
__netdev_find_upper_dev(,,deep=true/false) <-- find in all levels
__netdev_has_upper(,) <-- check only the one level.
