Subject: atl1c: fix issue of transmit queue 0 timed out
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b94e52f62683dc0b00c6d1b58b80929a078c0fd5;p=linux-beck.git

atl1c: fix issue of transmit queue 0 timed out

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.
