| 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. |
