"""
Note: To Run this script gui should be opened with

    path: cd LANforgeGUI_5.4.3 (5.4.3 can be changed with GUI version)
          pwd (Output : /home/lanforge/LANforgeGUI_5.4.3)
          ./lfclient.bash -cli-socket 3990

Note: This is a test file which will run a wifi capacity test.
    ex. on how to run this script:
    ./lf_wifi_capacity_test.py --mgr localhost --port 8080 --lf_user lanforge --lf_password lanforge
    --instance_name this_inst --config_name test_con --upstream 1.1.eth1 --batch_size 1 --loop_iter 1
    --protocol UDP-IPv4 --duration 6000 --pull_report --stations 1.1.sta0000,1.1.sta0002

Note:
    --pull_report == If specified, this will pull reports from lanforge to your code directory,
                    from where you are running this code

    --stations == Enter stations to use for wifi capacity
