From:	Tobias Klauser <tklauser@...tanz.ch>
To:	Chris Metcalf <cmetcalf@...era.com>, netdev@...r.kernel.org
Subject: [PATCH net-next-2.6] netdev: tilepro: Use is_multicast_ether_addr helper

Use is_multicast_ether_addr from linux/etherdevice.h instead of a custom
macro. Also remove the broadcast address check, as it is considered a
multicast address too.
