     35  * This support is optional; it is only used when the 802.11 layer's
     36  * authentication mode is set to use 802.1x or WPA is enabled separately
     37  * (for WPA-PSK).  If compiled as a module this code does not need

     41  * of the available callbacks--the user mode authenticator process works
     42  * entirely from messages about stations joining and leaving.
