[NET]: Network Event Notifier Mechanism.
This patch uses notifier blocks to implement a network event
notifier mechanism.
Clients register their callback function by calling
register_netevent_notifier() like this:
static struct notifier_block nb = {
.notifier_call = my_callback_func
};
...
register_netevent_notifier(&nb);
