had an odd issue on my openwrt router. my libtins app would worked fine until installing netem e.g. opkg install kmod-netem which depends on kmod-sched. After installing that, a new empty interface is created (at least on openwrt, not sure about other distros) that has no IP address.
I see no reason to throw an exception here. It is especially problematic because at least in my app, the interfaces are initialized when the program starts, I suppose in a constructor somewhere.
Simply removing this solves the issue. Perhaps a better approach would be to only throw an exception when a given interface is empty and chosen for us with a sniffer. I'm not exactly sure how kmod-sched uses the empty interface, but it may even be desirable to monitor such an interface.
In short.. I believe this check should be deleted or at least turned into something that doesnt abort a program.
