Currently, we store the statistics in the independent fields of virtnet_stats, this is not scalable when we want to add more counters. As suggested by Michael, this patch convert it to an array and use the enum as the index to access them.

To help in vhost analyzing, the following series adding basic tracepoints to vhost. Operations of both virtqueues and vhost works were traced in current implementation, net code were untouched. A top-like satistics displaying script were introduced to help the troubleshooting. TODO: - net specific tracepoints? --- Jason Wang (2): vhost: basic tracepoints tools: virtio: add a
