Thus anytime a unicast address is added to the bond, the bond is places in promiscuous mode. Turn on IFF_UNICAST_FLT on the bond device so that the bond does not go into promiscuous mode needlesly. If an underlying device does not support unicast filtering, that device will automaticall enter promiscuous mode already. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
