Add multiqueue support
Problem: Neither OVS nor SRIOV multi-queue is not supported. Guest VM lacks tuning to reach high throughput. Solution: (1) Build SRIOV multi-queue capable guest image by recompiling the igxbevf driver (make CFLAGS_EXTRA=-DIXGBE_ENABLE_VF_MQ install). (2) Change pktgen to send on multiple queues. (3) Add tuning in guest VM (Disable irqbalance and setup vNIC interrupt affinity to vCPUs) Update 1: Takes care comments plus adds unit test cases Update 2: Jenkins reports code coverage 81%, local reports 96%, add more unit test cases Update 3: Manually rebased to adapt to SSH.from_node() Update 4: Takes care comments for vnic_type, vnic_name Change-Id: Ieb15381c653b13697487d095efa4be6c3c49fa42 JIRA: YARDSTICK-619 Signed-off-by: Jing Zhang <jing.c.zhang@nokia.com>
