Execution Flow

1. For a wireless connection, keep the device's Wi-Fi disconnected before you executing ./wpa_supplicant
2. Use ./wpa_supplicant -h to list all parameter usage
3. Some situations listed below

// In wpa_supplicant sub-folder
// -c: configuration file
// -i: interface to listen
// -D: driver name
// -dd: show detail message
        
// 1. wireless connection
> sudo ./wpa_supplicant -c ../wpa_supplicant.conf -i <wifi interface name> -dd
        
// 2. wired conncetion (So far, this option has not been tested with TNGF)
> sudo ./wpa_supplicant -c ../wpa_supplicant.conf -i <wired interface name> -D wired -dd
