* 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.
