From 32361ffed1efce856e56a04029dcb72e5dcbf02d Mon Sep 17 00:00:00 2001 From: Christian Trautman Date: Mon, 15 Aug 2016 13:44:27 -0400 Subject: old_style_multi-queue: Allows for multi-queue with ovs <= 2.5.0 Enables multi-queue option for OVS versions 2.5.0 or less with dpdk. Instead of enabling MQ on a port by port basis this sets the global MQ option after starting the ovs switch.
