From 3170ff54c26004ea627022af695d0c8709d29b04 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Wed, 29 Jun 2011 02:15:15 +0000 Subject: net: depca: Omit check for multicast bit in netdev_for_each_mc_addr There is no need to check for the address being a multicast address in the netdev_for_each_mc_addr loop, so remove it.
