3.8.13.13 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: Sebastian Hesselbarth <sebastian.hesselba...@gmail.com>

[ Upstream commit 041b4ddb84989f06ff1df0ca869b950f1ee3cb1c ]

Each port driver installs a periodic timer to update port statistics
by calling mib_counters_update. As mib_counters_update is also called
from non-timer context, we should not reschedule the timer there but
rather move it to timer-only context.
