From: Jakob Meng <c...@jakobmeng.de> For better usability, the function pairs get_config() and set_config() for netdevs should be symmetric: Options which are accepted by set_config() should be returned by get_config() and the latter should output valid options for set_config() only. This patch also moves key-value pairs which are no valid options from get_config() to the get_status() callback.
The documentation in vswitchd/vswitch.xml for status columns has been updated accordingly.
