net: Convert ipvlan_net_ops
These pernet_operations unregister ipvlan net hooks. nf_unregister_net_hooks() removes hooks one-by-one, and then frees the memory via rcu. This looks similar to that happens, when a new hooks is added: allocation of bigger memory region, copy of old content, and rcu freeing the old memory. So, all of net code should be well with this behavior. Also at the time of hook unregistering, there are no packets, and foreign net pernet_operations are not interested in others hooks. So, we mark them as async. Signed-off-by: Kirill Tkhai <ktkhai@virtuozzo.com> Signed-off-by: David S. Miller <davem@davemloft.net>
