    See NetBSD mii source code too:
    They announce when a cable is plugged and unplugged on the routing socket.

    mii_physubr.c
     ...
    void
    mii_phy_update(struct mii_softc *sc, int cmd)
    {
            struct mii_data *mii = sc->mii_pdata;
            int announce, s;

            if (sc->mii_media_active != mii->mii_media_active ||
                sc->mii_media_status != mii->mii_media_status ||
                cmd == MII_MEDIACHG) {
                    announce = mii_phy_statusmsg(sc);
                    (*mii->mii_statchg)(sc->mii_dev.dv_parent);
                    sc->mii_media_active = mii->mii_media_active;
                    sc->mii_media_status = mii->mii_media_status;

                    if (announce) {
                            s = splnet();
                            rt_ifmsg(mii->mii_ifp);
                            splx(s);
                    }
            }
    }
