From: Vladimir Oltean <vladimir.oltean@xxxxxxx> commit 8043c845b63a2dd88daf2d2d268a33e1872800f0 upstream. Looking through patchwork I don't see that there was any consensus to use switchdev notifiers only in case of netlink provided port flags but not sysfs (as a sort of deprecation, punishment or anything like that), so we should probably keep the user interface consistent in terms of functionality. http://patchwork.ozlabs.org/project/netdev/patch/20170605092043.3523-3-jiri@xxxxxxxxxxx/ http://patchwork.ozlabs.org/project/netdev/patch/20170608064428.4785-3-jiri@xxxxxxxxxxx/ Fixes: 3922285d96e7 ("net: bridge: Add support for offloading port attributes") Signed-off-by: Vladimir Oltean <vladimir.oltean@xxxxxxx> Acked-by: Nikolay Aleksandrov <nikolay@xxxxxxxxxx> Signed-off-by: David S.
