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. JIRA: VSPERF-372 Change-Id: I245c76779695518d0005122d8214bbf3f141bb96 Signed-off-by: Christian Trautman <ctrautma@redhat.com>
