From: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>
This patch adds a new initialization function:
can_rx_offload_add_manual()
It should be used to add support rx-offload to a driver, if the callback
mechanism should not be used. Use can_rx_offload_receive_skb() (added in
the next patch) to queue skbs into rx-offload.
