atl1: Do not wake queue before queue has been started.
Based upon a bug report by Alexey Dobriyan, the patch is also tested by him and confirmed to fix the problem. Packet flow during link state events should not be done by waking and stopping the TX queue anyways, that is handled transparently by netif_carrier_{on,off}(). So, remove the netif_{wake,stop}_queue() calls in the link check code, and add the necessary netif_start_queue() call to atl1_up(). Signed-off-by: David S. Miller <davem@davemloft.net>
