Wait, scratch that. It's not "really hard", it's "almost impossible". At open() time, you have no idea which netlink family the program wants to communicate with. bind() is also hard. (In theory, you could support bind() on this new FD -- but then why is userspace using a file in the first place, and not a socket?) So this is even less of a serious suggestion now. I'd still like to be able to refer to NICs by multiple names though, if we can find a way that works...
