42 * External authenticator placeholder module.

44 * This support is optional; it is only used when the 802.11 layer's
45 * authentication mode is set to use 802.1x or WPA is enabled separately
46 * (for WPA-PSK). If compiled as a module this code does not need
47 * to be present unless 802.1x/WPA is in use.
48 *
49 * The authenticator hooks into the 802.11 layer. At present we use none
50 * of the available callbacks--the user mode authenticator process works
51 * entirely from messages about stations joining and leaving.
