From 4c9912556867bf89e7bb6946fd218a40b1d12139 Mon Sep 17 00:00:00 2001 From: Vlad Yasevich Date: Wed, 4 Jun 2014 16:23:37 -0400 Subject: [PATCH] macvlan: Support bonding events Bonding and team drivers generate specific events during failover that trigger switch updates. When a macvlan device is configured on top of bonding, we want switches to learn about the macvlan devices as well. This patch adds a handler to macvlan driver to propagate these events to all macvlan devices. We let the generic inetdev event handler do the work. This allows macvlan to operated correctly over active-backup mode bond. Signed-off-by: Vlad Yasevich Signed-off-by: David S.
