All other DPDK PMDs doesn't support concurrent receiving or sending packets to the same queue. The upper application should deal with this, normally through queue and core bindings. Due to historical reason, vhost internally supports concurrent lockless enqueuing packets to the same virtio queue through costly cmpset operation. This patch removes this internal lockless implementation and should improve performance a bit. Luckily DPDK OVS doesn't rely on this behavior.
