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
but netif_wake_queue isn't called when cable Link is resume.

If this fixes  a system hang then this could be a stable
fix -- that is, this should be propagated to older stable
kernels, no?

If so then please add to the commit log a line like this:

Cc: stable@vger.kernel.org [3.4]

Note: this is for the commit log! Right above the line below
that has "---"
