The reason why you saw dummynet coming in together with device driver patches is that at the same time i also added support for bridging, and that _did_ require working at the device driver (actually, it might have been done in ether_input() but with some loss of efficiency, and since there efficiency is critical i thought it was better to go as low as reasonably possible).
