Allow the user to set the IP address of the eapol_test client. This if very useful when you have a machine with many interfaces and want to use a particular one for testing RADIUS connectivity. For instance when I run the national eduroam proxy I can only connect to other server from a particular address, an our machine happens to have several IPs. So if I want to run connectivity tests, I must make sure that my test uses a particular interface. The -A option allows one to set this). (jm: cleaned up to use radius configuration structure instead of global variable for the address and added IPv6 support)
