Currently, one cannot change, add or remove addresses to/from tun 
interfaces with ifconfig. This makes sense for IPv4, but I suggest that 
this restriction be lifted for IPv6. Once link-local addresses have been 
negotiated, I don't particlarly see a reason why ordinary router 
solicitation / advertisement couldn't happen over the link outside the 
control of PPP. If we do not do this, then we will have to reimplement 
router solicitation / advertisement in PPP, which seems needless to me.
