    NAME: lf_interop_ping.py

    PURPOSE: lf_interop_ping.py will let the user select real devices, virtual devices or both and then allows them to run
    ping test for user given duration and packet interval on the given target IP or domain name.

    EXAMPLE-1:
    Command Line Interface to run ping test with only virtual clients
    python3 lf_interop_ping.py --mgr 192.168.200.103  --target 192.168.1.3 --virtual --num_sta 1 --radio 1.1.wiphy2 --ssid RDT_wpa2 --security wpa2
    --passwd OpenWifi --ping_interval 1 --ping_duration 1 --server_ip 192.168.1.61 --debug

    EXAMPLE-2:
    Command Line Interface to run ping test with only real clients
    python3 lf_interop_ping.py --mgr 192.168.200.103 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1 --server_ip 192.168.1.61 --ssid RDT_wpa2 --security wpa2_personal
    --passwd OpenWifi

    EXAMPLE-3:
    Command Line Interface to run ping test with both real and virtual clients
    python3 lf_interop_ping.py --mgr 192.168.200.103 --target 192.168.1.3 --real --virtual --num_sta 1 --radio 1.1.wiphy2 --ssid RDT_wpa2 --security wpa2
    --passwd OpenWifi --ping_interval 1 --ping_duration 1 --server_ip 192.168.1.61

    EXAMPLE-4:
    Command Line Interface to run ping test with existing Wi-Fi configuration on the real devices
    python3 lf_interop_ping.py --mgr 192.168.200.63 --real --target 192.168.1.61 --ping_interval 5 --ping_duration 1 --passwd OpenWifi --use_default_config

    EXAMPLE-5:
    Command Line Interface to run ping test by setting device specific Pass/Fail values in the csv file
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1 --device_csv_name device.csv
     --use_default_config

    EXAMPLE-6:
    Command Line Interface to run ping test by setting the same expected Pass/Fail value for all devices
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1 --expected_passfail_value 3
     --use_default_config

    EXAMPLE-7:
    Command Line Interface to run ping test by configuring Real Devices with SSID, Password, and Security
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1  --ssid RDT_wpa2 --security wpa2
    --passwd OpenWifi --server_ip 192.168.244.97 --wait_time 30

    EXAMPLE-8:
    Command Line Interface to run ping test by Configuring Devices in Groups with Specific Profiles
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1   --group_name grp3 --file_name g219 --profile_name Open5
     --server_ip 192.168.204.60

    EXAMPLE-9:
    Command Line Interface to run ping test by Configuring Devices in Groups with Specific Profiles with expected Pass/Fail values
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1   --group_name grp3 --file_name g219 --profile_name Open5
     --expected_passfail_value 3 --server_ip 192.168.204.60

    EXAMPLE-10:
    Command Line Interface for Configuring Devices in Groups with Specific Profiles with device_csv_name
    python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1   --group_name grp3 --file_name g219 --profile_name Open5
     --device_csv_name device.csv --server_ip 192.168.204.60

    SCRIPT_CLASSIFICATION : Test

    SCRIPT_CATEGORIES: Performance, Functional, Report Generation

    NOTES:
    1.Use './lf_interop_ping.py --help' to see command line usage and options
    2.Please pass ping_duration in minutes
    3.Please pass ping_interval in seconds
    4.After passing the cli, if --real flag is selected, then a list of available real devices will be displayed on the terminal.
    5.Enter the real device resource numbers seperated by commas (,)

        ping test for user given duration and packet interval on the given target IP or domain name.

        EXAMPLE-1:
        Command Line Interface to run ping test with only virtual clients
        python3 lf_interop_ping.py --mgr 192.168.200.103  --target 192.168.1.3 --virtual --num_sta 1 --radio 1.1.wiphy2 --ssid RDT_wpa2 --security wpa2

        EXAMPLE-5:
        Command Line Interface to run ping test by setting device specific Pass/Fail values in the csv file
        python3 lf_interop_ping.py --mgr 192.168.244.97 --real --target 192.168.1.3 --ping_interval 1 --ping_duration 1 --device_csv_name device.csv
