To create a stateful IPv6 DHCP environment, routing
advertisement messages must set the "managed" flag, may
optionally set the "other stateful" flag and must not include
any prefix information; including prefix information in
router advertisemessages explicitly allows clients to use
stateless address autoconfiguration.
rtadvd does not provide a configuration option to suppress
prefix info. If you do not explicitly specify one or more
"addr" options, rtadvd automatically discovers prefixes by
iterating over the interfaces.
Fix: The attached patches add a "noprefix" option to rtadvd.conf.
