[net-next-2.6 PATCH 2/6 RFC v3] net: Add netdev_ops to set and get MAC/VLAN rx filters

[Roopa Prabhu <roprabhu@cisco.com>]

From: Roopa Prabhu <roprabhu@cisco.com>

This patch adds the following netdev_ops to set and get MAC/VLAN
filters on a SRIOV VF or any netdev interface. Each op takes a vf argument.
vf value of SELF_VF or -1 is for applying the operation directly on the
interface.

ndo_set_rx_filter_addr - to set address filter
ndo_get_rx_filter_addr_size - to get address filter size
ndo_get_rx_filter_addr - To get addr filter

ndo_set_rx_filter_vlan - to set vlan filter
ndo_get_rx_filter_vlan_size - to get vlan filter size
ndo_get_rx_filter_vlan - To get vlan filter
