As the documentation for netif_trans_update() says, netdev_start_xmit() already updates the last-tx time after every good xmit. So don't duplicate that effort. One odd case is that qeth_flush_buffers() also gets called from our TX completion handler, to flush out any partially filled buffer when we switch the queue to non-packing mode. But as the TX completion handler will _always_ wake the txq, we don't have to worry about the TX watchdog there.
