Would it be worth bringing up the subject of adding an IFF_ flag that can be SIOCSIFFLAGS'd into the interface with the kame team ? Currently, ppp manages to control the link-local address every second time it's run on a given interface... which just looks weird :*I It seems more sane to allow a program to say ``I do my own address discovery''. If you think it's worth bringing up with the kame guys, can you tell me where I should send the mail (which list address) ?
