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.
