[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); Signed-off-by: Tom Tucker <tom@opengridcomputing.com> Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: David S.

[NET]: Remove unnecessary inclusion of dst.h The file net/netevent.h only refers to struct dst_entry * so it doesn't need to include dst.h. I've replaced it with a forward declaration. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
