'up' above, according to the documentation, is the DEVICE.

So the script uses undocumented features?
In that case a comment saying exactly that would be nice :)
But you don't need it, as the filter removes all but the LOWER_UP
interfaces.

And, by the way... By association the 'down' argument should also
work, shouldn't it?  But it doesn't:

$ ip link show down
Device "down" does not exist.
