I propose a patch which allows to mark a dst_entry as "non-reroutable".
icmp6_dst_alloc() (used by ndisc and MLD implementation) will always mark the
allocated dst_entry as such. A check is added to netfilter (IPv6-only) so
packets heading for a non-reroutable destination are never rerouted.

What about addrconf_dst_alloc()?  Shouldn't it have this new flag set
as well?

Regardless of the answer to that question, it should be explained
in the commit message.

Thanks.
