To quit, close xterms and run following docker kill cmd (WARNING: This will kill all docker containers!) ‘docker kill $(docker ps -q)’ Docker iPerf using default Linux Bridge :: $WS_ROOT/test/scripts/socket_test.sh -bi docker-kernel Docker iPerf using VPP :: $WS_ROOT/test/scripts/socket_test.sh -bi docker-preload
