[PATCH net-next] ipv6: Export nd_tbl to allow modules to support IPv6

[Thomas Graf <tgraf@suug.ch>]

Several out of the tree modules use the exported symbol arp_tbl
to read the ARP table. These modules now seek to support IPv6
but can't because nd_tbl is not exported.

Having access to the protocol specific neigh_table structure is
required in order to use the functions neigh_lookup() or
neigh_create() which are already exported to modules.

It does not make sense to export these functions if we don't
export the table itself as well.
