When running 'info network', if the stream backend is still in the process of connecting, or waiting for an incoming connection, no information is displayed. There is also no way to distinguish whether the server is still in the process of setting up the listener socket, or whether it is ready to accept incoming client connections. This leads to a race condition in the netdev-socket qtest which launches a server process followed by a client process. Under high load conditions it is possible for the client to attempt to connect before the server is accepting clients. For the scenarios which do not set the 'reconnect' option, this opens up a race which can lead to the test scenario failing to reach the expected state. Now that 'info network' can distinguish between initialization phase and the listening phase, the netdev-socket qtest will correctly synchronize, such that the client QEMU is not spawned until the server is ready. This should solve the non-deterministic failures seen with the netdev-socket qtest. Signed-off-by: Daniel P.
