Hey Konstantin,
This method does reduce code size but lead to significant performance drop.
I think we need to keep the original code.

Hi Tetsuya,
In my test I created 2 vdev using "--vdev
'eth_vhost0,iface=/tmp/sock0,queues=1' --vdev
'eth_vhost1,iface=/tmp/sock1,queues=1'", and the qemu message got handled in
wrong order.
The reason is that: 2 threads are created to handle message from 2 sockets, but
their fds are SHARED,

#elif works with statements:
