There is following idea: The inbound processing of the qeth driver is already in bottomhalf (qdio input tasklet) so we can switch from netif_rx to netif_receive_skb. This allows us to exploit gro code for the layer 3 driver. I would introduce a dummy napi_struct and call napi_gro_flush when the inbound tasklet ends. Should I post the patch for review?
