"""
NAME: test_ipv4_l4_ftp_wifi.py

PURPOSE:
test_ipv4_l4_ftp_wifi.py will create stations and endpoints to generate and verify layer-4 traffic over an ftp connection

This script will monitor the bytes-wr attribute of the endpoints. If the the monitored value does not continually increase, this test will not pass.

EXAMPLE:
./test_ipv4_l4_ftp_wifi.py --upstream_port eth1 --radio wiphy0 --num_stations 3 --security {open|wep|wpa|wpa2|wpa3}
    --ssid netgear --passwd admin123 --dest 10.40.0.1 --test_duration 2m --interval 1s --requests_per_ten 600
    --dest /var/www/html/data_slug_4K.bin --source /tmp/data_slug_4K.bin --ftp_user lanforge --ftp_passwd lanforge
    --debug
