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) ? Thanks.
