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