From 041b4ddb84989f06ff1df0ca869b950f1ee3cb1c Mon Sep 17 00:00:00 2001 From: Sebastian Hesselbarth Date: Wed, 2 Oct 2013 12:57:20 +0200 Subject: net: mv643xx_eth: update statistics timer from timer context only 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.
