Merge patch series "can: gs_usb: convert to NAPI"
Marc Kleine-Budde <[email protected]> says: Traditionally USB drivers used netif_rx to pass the received CAN frames/skbs to the network stack. In netif_rx() the skbs are queued to the local CPU. If IRQs are handled in round robin, CAN frames may be delivered out-of-order to user space. To support devices without timestamping the TX path of the rx-offload helper is cleaned up and extended: - rename rx_offload_get_echo_skb() -> can_rx_offload_get_echo_skb_queue_timestamp() - add can_rx_offload_get_echo_skb_queue_tail() The last patch converts the gs_usb driver to NAPI with the rx-offload helper.
