Subject: [PATCH 052/109] 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.
