401 * an interface, logical or not, goes ~IFF_UP).
403 * Ie, we mangle IFF_UP to *additionally* reflect whether or not there
404 * are addresses left in struct connected, not just the actual underlying
407 * We must hence remember the real state of IFF_UP, which we do in
408 * struct zebra_if.primary_state.
410 * Setting IFF_UP within zebra to administratively shutdown the
