It happened on a different mail thread, and I haven't done any comparison with ovsdb drivers. http://lists.openstack.org/pipermail/openstack-dev/2016-April/091639.html http://lists.openstack.org/pipermail/openstack-dev/2016-April/091642.html > Any chance that we document these choices yet? I've put a patch that switches to the native of_interface. If we cannot switch the default, better documentation might help. > Clark > -- IWAMOTO Toshihiro __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
