NAME: test_l4.py

PURPOSE:
test_l4.py will create stations and endpoints to generate and verify layer-4 traffic

This script will monitor the urls/s, bytes-rd, or bytes-wr attribute of the endpoints.
These attributes can be tested over FTP using a --ftp flag.
If the the monitored value does not continually increase, this test will not pass.

This script replaces the functionality of test_ipv4_l4.py, test_ipv4_l4_ftp_upload.py, test_ipv4_l4_ftp_urls_per_ten.py,
test_ipv4_l4_ftp_wifi.py, test_ipv4_l4_urls_per_ten.py, test_ipv4_l4_urls_per_ten.py, test_ipv4_l4_wifi.py

EXAMPLE (urls/s):
    ./test_l4.py --upstream_port eth1 --radio wiphy0 --num_stations 3 --security {open|wep|wpa|wpa2|wpa3}
                 --ssid netgear --passwd admin123 --requests_per_ten 600 --mode   1 --num_tests 1 --test_type 'urls'
                 --url "dl http://10.40.0.1 /dev/null" --ap "00:0e:8e:78:e1:76" --target_per_ten 600 --output_format csv
                 --report_file ~/Documents/results.csv --test_duration 2m --debug

EXAMPLE (bytes-wr):
    ./test_l4.py --upstream_port eth1 --radio wiphy0 --num_stations 3 --security {open|wep|wpa|wpa2|wpa3}
                 --ssid netgear --passwd admin123 --test_duration 2m --url "ul http://10.40.0.1 /dev/null"
                 --requests_per_ten 600 --test_type bytes-wr --debug

EXAMPLE (bytes-rd):
    ./test_l4.py --upstream_port eth1 (optional) --radio wiphy0  (required) --num_stations 3 (optional)
                 --security {open|wep|wpa|wpa2|wpa3} (required) --ssid netgear (required)
                 --url "dl http://10.40.0.1 /dev/null" (required) --password admin123 (required)
                 --test_duration 2m (optional) --test_type bytes-rd --debug (optional)

EXAMPLE (ftp urls/s):
    ./test_l4.py --upstream_port eth1 --radio wiphy0 --num_stations 3 --security {open|wep|wpa|wpa2|wpa3}
                 --ssid netgear --passwd admin123 --test_duration 2m --interval 1s --mode 1 --ap "00:0e:8e:78:e1:76"
                 --requests_per_ten 600 --num_tests 1 --ftp --test_type 'urls'
                 --url "ul ftp://lanforge:lanforge@10.40.0.1/example.txt  /home/lanforge/example.txt" --debug

EXAMPLE (ftp bytes-wr):
    ./test_l4.py --upstream_port eth1 --radio wiphy0 --num_stations 3 --security {open|wep|wpa|wpa2|wpa3}
                 --ssid netgear --passwd admin123 --test_duration 2m --url "ul ftp://10.40.0.1 /dev/null"
                 --requests_per_ten 600 --ftp --test_type bytes-wr --debug

EXAMPLE (ftp bytes-rd):
    ./test_l4.py --upstream_port eth1 (optional) --radio wiphy0  (required) --num_stations 3 (optional)
                 --security {open|wep|wpa|wpa2|wpa3} (required) --ssid netgear (required)
