-/*
- * Each event has associated to it
- * - an event type (see constants in public header)
- * - an event context (see below)
- * - the function to be called
- * - a context (extra parameter to call the function with)
- * - and the softmac struct
- *
- * The event context is private and can only be used from
- * within this module. Its meaning varies with the event
- * type:
- * SCAN_FINISHED,
- * DISASSOCIATED: NULL
- * ASSOCIATED,
- * ASSOCIATE_FAILED,
- * ASSOCIATE_TIMEOUT,
- * AUTHENTICATED,
- * AUTH_FAILED,
- * AUTH_TIMEOUT: a pointer to the network struct
- * ...
- * Code within this module can use the event context to be only
- * called when the event is true for that specific context
- * as per above table.
- * If the event context is NULL, then the notification is always called,
- * regardless of the event context. The event context is not passed to
- * the callback, it is assumed that the context suffices.
- *
- * You can also use the event context only by setting the event type
- * to -1 (private use only), in which case you'll be notified
- * whenever the event context matches.
