Hi,
Can anybody tell me if it's possbile to tell a given interface not to
do DAD ? Specifically, when using the tun device for PPP, PPP
negotiates it's own endpoint (link-local) addresses with the peer.
However, it doesn't look possible to stop the kernel from doing DAD
unless we already have a link-local address assigned to the interface
when we IFF_UP it....
Perhaps we could have a new IFF_ flag (say, IFF_NODAD) that could be
ioctl()d into the interface's if_flags field and checked in
in6_ifattach() ?
Thanks for any help....
