wlan-lanforge-scripts/py-scripts/lf_wifi_capacity_test.py

"""
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.py --lfmgr "localhost" --port 8080 --lf_usr lanforge --lf_pswd lanforge
    --instance_name "this_inst" --config_name "test_con" --upstream eth1 --batch_size 1 --loop_iter 1
    --protocol "UDP-IPv4" --duration 6000 --pull_report y --auto_add n --stations sta0000

Note:
    --pull_report == keep it to y, if you want wifi capacity reports at end of the test.
                    This will pull reports from lanforge to your code directory,
                    from where you are running this code
                    keep this to n, if you are running this from lanforge

    --auto_add == if you dont want to add stations manually to wifi capacity test.
                keep this as y: This will automatically add all the stations to test
                if selected as n: Give station names in --stations argument
    --stations == if --auto_add is n, enter stations to use for wifi capacity
