vlan: turn on unicast filtering on vlan device
Currently vlan device inherits unicast filtering flag from underlying device. If underlying device doesn't support unicast filter, this will put vlan device into promiscuous mode when it's stacked. Tun on IFF_UNICAST_FLT on the vlan device in any case so that it does not go into promiscuous mode needlessly. If underlying device does not support unicast filtering, that device will enter promiscuous mode. Signed-off-by: Zhang Shengju <zhangshengju@cmss.chinamobile.com> Signed-off-by: David S.
