[Spice-devel] [PATCH v2 spice-common 5/5] Add qos related messages

[Yonit Halperin]

If the client's channel has SPICE_COMMON_CAP_QOS_QUERY,
the server's channel can send SPICE_MSG_QOS_QUERY to the client.
In response, the client is expected to send back SPICE_MSG_QOS_ACK
immediately after it receives the message following the query, and
before handling the message. The server can deduce
the network conditions using the ack arrival time.
