From 32092ecf0644e91070f9eff4f6e1edda8f90aecc Mon Sep 17 00:00:00 2001
From: David Miller <davem@davemloft.net>
Date: Mon, 25 Jul 2011 00:01:41 +0000
Subject: atm: clip: Use device neigh support on top of "arp_tbl".

Instead of instantiating an entire new neigh_table instance
just for ATM handling, use the neigh device private facility.
