[PATCH net-next 3/6] net: Convert ovs_net_ops

[Kirill Tkhai <ktkhai@xxxxxxxxxxxxx>]

These pernet_operations initialize and destroy net_generic()
data pointed by ovs_net_id. Exit method destroys vports from
alive net to exiting net. Since they are only pernet_operations
interested in this data, and exit method is executed under
exclusive global lock (ovs_mutex), they are safe to be executed
in parallel.
