From c565b488c6a86fdff24f6d716defc3d07a474b44 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 4 Jun 2014 16:23:36 -0400 Subject: [PATCH] bonding: Turn on IFF_UNICAST_FLT on bond devices Bonding devices manage the unicast filters of the underlying interfaces, but do not turn on IFF_UNICAST_FLT flag. 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.
