From 498d8e236304a62a2774d7264bdff2c6e8102b5b Mon Sep 17 00:00:00 2001
From: Tobias Klauser <tklauser@distanz.ch>

Subject: [PATCH] drivers/net: 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. This patch covers all
remaining network drivers still containing such a check.
