#!/bin/bash

#  This script is an attempt to simplify the creation of stations and connections for said stations.
#  One UDP connection will be created for each station.
#  The number of stations, station SSID, encryption type and passphrase, number of packets to send, and transmit rates
#  can all be configured with the below options.
#  Required values are SSID, radio, and endpoint A port.
#  -m   Manager IP or hostname.
#  -r   Resource number.
#  -w   Which radio to use i.e. wiphy0 wiphy1 etc.
#  -n   Number of stations to create.
#  -s   SSID for stations.
#  -e   Encryption type: open|wep|wpa|wpa2.
#  -k   Passphrase for when AP is encrypted.
#  -a   The upstream port to which station(s) will connect.
#  -A   Transmit rate for non station side (Endpoint A) of connection.
#  -B   Transmit rate for station side (Endpoint B) of connection.
#  -p   Number of default UDP sized packets to send.
#  -h   Help information.

#  Example usage:
#  ./lf_wifi_fire.bash -m lf0350-1234 -r 1 -w wiphy0 -n 40 -s test-SSID -e wpa2 -P hello123 -a eth1 -A 56000 -B 2000000 -p 10000

#  Station will always be endpoint B so only the name for endpoint A port is needed.
