That is not possible too. I hold the QDISC_RUNNING bit in dev->state and am the only sender for this device, so there is no other failed transmit. Also, on failure of dev_hard_start_xmit, qdisc_restart will spin for the queue lock (which could be held quickly by enqueuer's), and q->requeue() skbs to the head of the list.
