Add /usr/local/sbin/ppp-ipv6 helper script
/usr/local/sbin/ppp-ipv6 <real interface> up|down Interface using SLAAC or DHCP6 going down: * bring down dhcp6c if it is running * disable router advertisements (and therefore SLAAC) * remove any autoconfigured IPv6 addresses Interface using SLAAC or DHCP6 coming up: * call interface_dhcpv6_configure() if dhcp6c not running and router advertisements off interface_dhcpv6_configure() will enable router advertisements, configure rtsold and dhcp6c, then set rtsold to prime dhcp6c as required.
