events when (de)associating or when cable is (un)plugged

[Vincent Jardin]

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);
                }
        }
}
