[NET]: dev: secondary unicast address support
Add support for configuring secondary unicast addresses on network devices. To support this devices capable of filtering multiple unicast addresses need to change their set_multicast_list function to configure unicast filters as well and assign it to dev->set_rx_mode instead of dev->set_multicast_list. Other devices are put into promiscous mode when secondary unicast addresses are present. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
