>Description:
        kue(4) cannot receive multicast packets
        because in the case of SIOC{ADD,DEL}MULTI kue_ioctl() does not
        call ether_ioctl() to rebuild list of ec_multiaddrs before
        calling kue_setmulti().

>How-To-Repeat:
        assign kue ipv6 address and ping6 from other host.

>Fix:
        In the case of SIOC{ADD,DEL}MULTI please call ether_ioctl()
        to fill list of ec_multiaddrs before calling kue_setmulti().
