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);
}
}
}
