* External authenticator placeholder module.
*
* This support is optional; it is only used when the 802.11 layer's
* authentication mode is set to use 802.1x or WPA is enabled separately
* (for WPA-PSK). If compiled as a module this code does not need
* to be present unless 802.1x/WPA is in use.
*
* The authenticator hooks into the 802.11 layer. At present we use none
* of the available callbacks--the user mode authenticator process works
* entirely from messages about stations joining and leaving.
