NAME: test_ip_variable_time.py
PURPOSE:
test_ip_variable_time.py will create stations and endpoints to generate and verify layer-3 traffic over ipv4 or ipv6.
This script replaces the functionality of test_ipv4_variable_time.py and test_ipv6_variable_time.py
This Script has two working modes:
Mode 1:
When station is not available,
This script will create a variable number of stations each with their own set of cross-connects and endpoints.
It will then create layer 3 traffic over a specified amount of time, testing for increased traffic at regular intervals.
This test will pass if all stations increase traffic over the full test duration.
Mode 2:
When station is already available This script will create layer3 cross-connects and endpoints It will then
create layer 3 traffic over a specified amount of time, testing for increased traffic at regular intervals.
This test will pass if all stations increase traffic over the full test duration.
Use './test_ip_variable_time.py --help' to see command line usage and options

** FURTHER INFORMATION **
Using the layer3_cols flag:
Currently the output function does not support inputting the columns in layer3_cols the way they are displayed in the GUI. This quirk is under construction. To output
certain columns in the GUI in your final report, please match the according GUI column display to it's counterpart to have the columns correctly displayed in
your report.

This script uses two args parsers one in the script the second is Realm args parser
Realm args parser is one directory up then traverse into /py-json/LANforge/lfcli_base.py
search for create_basic_argsparse

Example command:
1. Use Existing station , Note: put the resource.shelf.wifi-sta (below is 1.1.wlan4),
The station needs to configured with the ssid, passwd, security and mode in the LANforge GUI

--layer3_cols 'name','tx rate','rx rate' --port_mgr_cols 'alias','channel','activity','mode'
--use_existing_sta --sta_names 1.1.wlan4
2. Create a one station (script default is 1 if --num_stations not entered)
./test_ip_variable_time.py --mgr 192.168.0.100 --radio wiphy6 --ssid ssid_5g --passwd pass_5g
--security wpa2 --test_duration 60s --output_format csv --traffic_type lf_tcp

--layer3_cols 'name','tx rate','rx rate' --port_mgr_cols 'alias','channel','activity','mode'
3. Create two stations
./test_ip_variable_time.py --mgr 192.168.0.100 --radio wiphy1 --ssid ssid_5g --passwd pass_5g
--security wpa2 --test_duration 60s --output_format csv --traffic_type lf_tcp
--a_min 600000000 --b_min 600000000 --upstream_port eth2 --mode '5'
