Vanilla_Multi_Queue: Add vanilla ovs multi-queue functionality
Adds multi-queue for vanilla OVS using virtio-net. TunTap ports will use multi_queue parameter when ports are created/deleted if guest nic queues are enabled and vswitch is ovs vanilla. Virtio net will now add guest nic queues to qemu command line if appropriate. Reworked multi-queue documentation to reflect these changes. Adds vhost net thread affinitization which is recommended when performing vanilla ovs multi-queue. Guests will require ethtool if using l2fwd or linux bridge as the loopback application when vanilla ovs multi-queue is enabled. Modified dpdk setting in vswitch conf to be better worded for separation from vanilla ovs multi-queue. Updated release and installation doc for new vloop image that includes required ethtool utility. JIRA: VSPERF-373 Change-Id: Idb550515190b1a93390308c11f54da368f962512 Signed-off-by: Christian Trautman <ctrautma@redhat.com>
