Subject: [net-next-2.6 PATCH 7/8 RFC v2] macvtap: Add support to set MAC/VLAN
	filter rtnl link operations

From: Roopa Prabhu <roprabhu@...co.com>

This patch adds support to set MAC and VLAN filter rtnl_link_ops
on a macvtap interface. It adds support for set_rx_addr_filter and
set_rx_vlan_filter rtnl link operations. These operations inturn call the
equivalent operations defined in macvlan
