The net engine was updated with specific 'listen' parameter which used
for identifying whether it is a tcp server, instead of previous
'rw=read' side must be the server. This let fio support bi-direction
net io test. fio_netio_open_file() has to follow this
principle. Otherwise, the following tcp client 'rw=read' and tcp
server 'rw=write' case doesn't work.
[global]
ioengine=net
port=8888
protocol=tcp
bs=4k
size=10g
[server]
listen
rw=write
[client]
hostname=localhost
startdelay=1
rw=read
BTW, examples/netio needs 'listen' and 'hostname' adjusted.
