There is a C library, libynl that abstracts a lot of the netlink
stuff away and is quite nice. That said, if you wanted to use it
from a script, you'd probably need bindings for it in the language
of your choice.

If you meant more a shell script type setup, then yea.... the python
CLI is (AFAIK) the only option.
