rt2500apd - user space IEEE 802.1X Authenticator
          for SoftAP driver for RT2500 b/g, Ralink Tech Corp.
=================================================================

Introduction
===========================
rt2500apd is an optional user space component for RT2500 SoftAP driver. 
It adds 802.1x Authenticator feature using external RADIUS Authentication
Server(AS).
 

IEEE 802.1X features in rt2500apd
===========================
IEEE Std 802.1X-2001 is a standard for port-based network access
control. It introduces a extensible mechanism for authenticating 
and authorizing users.

rt2500apd implements partial IEEE 802.1x features that helps AS authenrizing
Supplicant and in the mean time proves itself a valid Authenticator for AS.
Noticed that Key management state machine is not included in rt2500apd. 
And those key management is included in RT2500 SoftAp driver.

rt2500apd relays the frames between the Supplicant and the AS.
Not until either one timeout or Success or Fail frame
indicated does rt2500apd finish the authentication process.
The port control entity is implemented in SoftAp driver for RT2500.
