+Subject: atl1c: fix issue of transmit queue 0 timed out
+
+commit b94e52f62683dc0b00c6d1b58b80929a078c0fd5 upstream.
+
+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.
