From: Jiri Pirko <jpirko@...hat.com>
To: netdev@...r.kernel.org
Cc: davem@...emloft.net
Subject: [net-next-2.6 PATCH] staging: convert to use netdev_for_each_mc_addr
removed needless checks in arlan-main.c and slicoss.c
fixed bug in et131x_netdev.c to actually fill addresses in.
Signed-off-by: Jiri Pirko <jpirko@...hat.com>
