        usmsc(4) cannot change it's link address
        because the driver does not update sc with new link address in ifp
        when it's link address has been changed.

        assign another link address on usmsc, ifconfig usmsc down up, and
        ping other host.

        Please memcpy CLLADDR(ifp->if_sadl) to sc->sc_enaddr before
        calling smsc_setmacaddress().
