From: Alejandro Concepcion Rodriguez <alejandro@xxxxxxxx> netif_rx() is meant to be called from interrupt contexts. can_restart() may be called by can_restart_work(), which is called from a worqueue, so it may run in process context. Use netif_rx_any_context() which invokes the correct code path depending on context.
