- * The device state field, defines the initial state in which the

- * state.
- *
- * Things have changed here. I've killed timer1 since it's a user space
- * issue for a user space routing deamon to sort out. The kernel does
- * not need to be bothered with it.
- *
- * Timers:
- * t2 - Rate limit timer, min time between routing and hello messages
- * t3 - Hello timer, send hello messages when it expires
- *
- * Callbacks:
- * up() - Called to initialize device, return value can veto use of
- * device with DECnet.
- * down() - Called to turn device off when it goes down
- * timer3() - Called once for each ifaddr when timer 3 goes off
