As Ziyang Xuan stated, the patch was not applied to upstream. Usage of WARN_ON_ONCE in this case is actually discouraged: it erroneusly complains in a valid situation. So the macro should be removed with the aforementioned patch. If it makes some sense for debugging purposes, WARN_ON_ONCE can be replaced with netdev_warn/netdev_notice but anyway discard of WARN_ON_ONCE. -- Regards, Fedor
