35 * This support is optional; it is only used when the 802.11 layer's
36 * authentication mode is set to use 802.1x or WPA is enabled separately
37 * (for WPA-PSK).  If compiled as a module this code does not need
38 * to be present unless 802.1x/WPA is in use.

40 * The authenticator hooks into the 802.11 layer.  At present we use none

42 * entirely from messages about stations joining and leaving.
