Indeed; thanks for taking this on. Would it also be useful to have an
API that simply sets the network and mask of the default network?

Any interest in doing this with netlink instead? (I've got this
"thing" against parsing text files to get information if it can be
retrieved via a nice clean API). If so, I think I can whip up the
equivalent code with libnl calls, but probably not until later in
the afternoon.
I agree, using netlink would be a bit cleaner.
