    Subject[PATCH 1/1] atl1c: fix issue of transmit queue 0 timed out
    Date
    some people report atl1c could cause system hang with following
    kernel trace info:
    ---------------------------------------
    WARNING: at.../net/sched/sch_generic.c:258 dev_watchdog+0x1db/0x1d0()
    ...
    NETDEV WATCHDOG: eth0 (atl1c): transmit queue 0 timed out
    ...
    ---------------------------------------
    This is caused by netif_stop_queue calling when cable Link is down.
    So remove netif_stop_queue, because link_watch will take it over.
