Subject: ovs-save: Use timeout option for ovs-vsctl
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=49770faf0d497e2a0b07f43163728c17b3e7363b;p=openvswitch

ovs-save: Use timeout option for ovs-vsctl

Running ovs-save directly to save datapath configuration can
wait forever if ovsdb-server is not running. Use a timeout.
