This makes only sense if we have another layer call e.g. calling the driver_ops which is done by callbacks like "set_channel". For MAC settings which need to be set by phy registers (if the phy supports that handling) this is set by doing an interface up currently and are not direct driver_ops calls, so we remove the checks from these configuration callbacks.
