Merge patch series "can: gs_usb: convert to NAPI"
Marc Kleine-Budde <mkl@pengutronix.de> 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.
