ethernet: T3163: not all NIC drivers support ring-buffer configuration
In addition to commit cf1156a60e ("ethernet: T3163: probe driver for maximum rx/tx ring-buffer size") this extends the logic in a way as not every driver supports setting the buffers at all so it will properly error out. When invoking "ethtool -g" both stdout and stderr are captured and no exception is raised if it's an unsupported driver feature. The verify() section will inform the user about the illegal operation.
