ncprange structure. Don't write() the netmask for IPv6 sockaddrs to the routing socket if the prefixlen is 128. It seems that messages written to the routing socket with the scopeid set for link local addresses are not understood. Instead, we have to put the scopeid in the 5th and 6th bytes of the address (see adjust_linklocal() in ncpaddr.c). I think this may be a bug in the KAME implementation - it should really understand both forms.
