Subject: [net-next-2.6 PATCH 6/6 RFC v3] macvlan: Add support to get MAC/VLAN
filter netdev ops
From: Roopa Prabhu <roprabhu@...co.com>
This patch adds support to get MAC and VLAN filter netdev ops
on a macvlan interface. It adds support for get_rx_filter_addr_size,
get_rx_filter_vlan_size, fill_rx_filter_addr and fill_rx_filter_vlan
netdev ops
