[j-nsp] Dcd complains about duplicate IPv6 link-local address

[Josef Buchsteiner]

Matti,
         this is just a warning and will not cause you
any troubles. In version 5.5 and higher we don't send
such warnings in this case as the link-local address
will be the same for all logical links for one atm-interface.


thanks
Josef
