>Description:
        msk(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.

>How-To-Repeat:
        assign another link address on msk, ifconfig msk down up, and
        ping from other host.

>Fix:
        Please fill sc_if->sk_enaddr with CLLADDR(ifp->if_sadl) before
        writing to unicast filter registers in msk_init_yukon().
