This patch set introduces 2 more vhost user messages: VHOST_USER_GET_QUEUE_NUM, for querying how many queues the backend supports, and VHOST_USER_SET_VRING_FLAG, for enabling/disabling a specific virt queue. Both of th two new messages are treated as vhost protocol extension, and that's why Michaels's patch "vhost-user: add protocol feature negotiation" is also included here. Patch 1-5 are all prepare work for actually enabling multiple queue. Patch 6 is the key patch for enabling multiple queue, which address two major concerns from Michael: no feedback from backend if it can't support # of requested queues, and all messages are sent N time. It also fixes an hidden bug. Patch 7 introduces the VHOST_USER_SET_VRING_FLAG message. Note that I haven't done any formal test yet, it just passes build test and basic functional test, such as it does exit when backend doesn't support # of requested queues. Here I sent it out just for more comments, and for avoiding spending too much effort on the wrong track.
