Provide Calling-Station-ID to RADIUS backed VPN connections
I'm using Duo 2fa radius proxy to connect to the on board RADIUS server in PFsense and am not getting an IP or a username in the Duo Notifications. This is a much valued feature to validate that the request is coming from one of my machines (I'm not always there when secneg occurs). I do not know the RADIUS attribute for username.

- Category set to Authentication
Might not be possible to put the client address in there since I am not sure the auth system will see that from OpenVPN/IPsec, but it might be worth looking into.
There have been changes since this request was made, however. It does fill in the NAS-IP-Address (configurable in the auth server settings) and NAS-Identifier, which will show at least which firewall the request came through.

Calling-Station-Id is already supported by EAP-RADIUS strongswan plugin, see https://wiki.strongswan.org/projects/strongswan/wiki/EAPRadius#Attributes-sent-to-RADIUS-servers

in case of OpenVPN, the current implementation of openvpn-plugin-auth-script.so do not support $clientid environment variable
