From eeb8467eec55dc5808bfc4ca1e1f6a49275c51d5 Mon Sep 17 00:00:00 2001 From: Arun Sharma Date: Wed, 16 May 2012 11:39:55 -0700 Subject: [PATCH] ovs-vsctl: Add "--all" option for "destroy" command in ovs-vsctl. Adds the ability to delete all records from table. This will help users to destroy all records from Qos or Queue table using single command rather then current method.
