From 7c6a3ed5bd61ec981c8a0d0111cfd435adf3f2b7 Mon Sep 17 00:00:00 2001 From: Ursula Braun <ursula.braun@de.ibm.com> Date: Wed, 26 Aug 2009 02:01:10 +0000 Subject: [PATCH] qeth: display "undefined" value of sysfs-attribute "layer2" If nothing has been written into the qeth sysfs-attribute layer2, its value is "-1" meaning "not yet defined". But the value is displayed as "1" meaning "layer2 selected". The patch changes the reading of this "-1"-value to "-1" to make clear the layer2-attribute has not yet been defined.
