28 * The dn_dev_parms structure contains the set of parameters
29 * for each device (hence inclusion in the dn_dev structure)
30 * and an array is used to store the default types of supported
31 * device (in dn_dev.c).
33 * The type field matches the ARPHRD_ constants and is used in
34 * searching the list for supported devices when new devices
37 * The mode field is used to find out if a device is broadcast,
38 * multipoint, or pointopoint. Please note that DECnet thinks
39 * different ways about devices to the rest of the kernel
40 * so the normal IFF_xxx flags are invalid here. For devices
41 * which can be any combination of the previously mentioned
42 * attributes, you can set this on a per device basis by
43 * installing an up() routine.
45 * The device state field, defines the initial state in which the
46 * device will come up. In the dn_dev structure, it is the actual
49 * Things have changed here. I've killed timer1 since it's a user space
50 * issue for a user space routing deamon to sort out. The kernel does
51 * not need to be bothered with it.
54 * t2 - Rate limit timer, min time between routing and hello messages
55 * t3 - Hello timer, send hello messages when it expires
58 * up() - Called to initialize device, return value can veto use of
60 * down() - Called to turn device off when it goes down
61 * timer3() - Called once for each ifaddr when timer 3 goes off
63 * sysctl - Hook for sysctl things
