From 61345fab484b97cca47149c90396c74ac76072f5 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 13 Dec 2018 11:54:41 +0000 Subject: [PATCH] net: ipvlan: Issue NETDEV_PRE_CHANGEADDR A NETDEV_CHANGEADDR event implies a change of address of each of the IPVLANs of this IPVLAN device. Therefore propagate NETDEV_PRE_CHANGEADDR to all the IPVLANs. Signed-off-by: Petr Machata Acked-by: Jiri Pirko Reviewed-by: Ido Schimmel Signed-off-by: David S.
