A few packets may still be sent and received during the termination of the iperf processes. These late packets cause failures when they arrive on queues expected to be empty.
Add a one second delay between repeated _send_traffic_check() calls in rss_ctx tests to ensure such packets are processed before the next traffic checks are performed.
Sprinklings sleeps should be last resort. Is there a way to wait for iperf to shut down cleanly, or wait for the socket to be closed fully? Like wait_port_listen() ?
The socket may end up in TIME_WAIT state, so waiting for it to be fully closed can take ~2 mins.
TIME_WAIT is as good as CLOSED for our purposes. Once we got a FIN the chances of more traffic should be minuscule.
