3.10-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.
