[lnst] NetTestController: always save config_only configuration
by Jiří Pírko 28 Feb '14

28 Feb '14

commit 8cadf4b8d938107832eebfbb70957f672c5de146 Author: Ondrej Lichtner <olichtne(a)redhat.com> Date: Fri Feb 28 15:58:15 2014 +0100 NetTestController: always save config_only configuration Until now we only saved config_only configuration if the run was virtualized, this was so that we could nicely deconfigure dynamically created network devices. This commit makes it so that the configuration is stored for every config_only run, even if virtualization wasn't used. This is not required for functionality since slaves will automatically deconfigure themselves when needed, but it can be used to call deconfiguration without running a different config_only run or run an entire recipe.
