From 7a1e4ef606a814b124fc35136c2821484981e6cb Mon Sep 17 00:00:00 2001 From: "Robin H. Johnson" Date: Fri, 2 Mar 2012 19:54:48 +0000 Subject: Bug #405491: _exists can give a false negative since /proc/net/dev can be slow to update sometimes when interfaces are added rapidly. Use sysfs instead. Signed-off-by: Robin H.
