One issue left. Since IPv6 is configured statically here, the  
preferred- and valid lifetimes are 'forever' (represented as  
0xffffffff). If the lifetime is forever, it should stay that way. See  
attached patch. It does not deal with the situation where  
addr[i].{preferred,valid} < now, in which case the value may need to  
be clamped to 0 or 1. I'm not sure if this can ever happen though.

I saw negative preferred- and valid lifetimes in my NetworkManager  
logs, because the latter has broken logging. These values are unsigned  
integers, but they are logged as signed integers (hence the negative  
values in the logs).
