+ * 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.
