From bbe14f54297467ddb23b7d1db564a2468c6ae151 Mon Sep 17 00:00:00 2001 From: Ido Schimmel Date: Fri, 13 Nov 2015 13:06:12 +0200 Subject: [PATCH] switchdev: bridge: Check return code is not EOPNOTSUPP When NET_SWITCHDEV=n, switchdev_port_attr_set simply returns EOPNOTSUPP. In this case we should not emit errors and warnings to the kernel log. Reported-by: Sander Eikelenboom Tested-by: Christian Borntraeger Fixes: 0bc05d585d38 ("switchdev: allow caller to explicitly request attr_set as deferred") Fixes: 6ac311ae8bfb ("Adding switchdev ageing notification on port bridged") Signed-off-by: Ido Schimmel Signed-off-by: Jiri Pirko Signed-off-by: David S.
