Not even image sensors. They just output the frame data; if the receiver runs out of buffers the data is just lost. And if any part of the frame is lost, there's no use for other parts of it either. But that's something the receiver must handle, i.e. discard the data and increment frame number (field_count in v4l2_buffer). The interfaces used by image sensors, be they parallel or serial, do not provide means to inform the sensor that the receiver has run out of buffer space. These interfaces are just unidirectional.
