* Need _rcu on the list_for_each_entry in br_get_port because called in
  read path for some ioctls
* Move two small functions is_root_bridge and is_designated_port into
  inlines because they are so short.

Thanks to Rusty for spotting this one, if the net family module is not there
anymore (or is going away at that time) it is not supported, not busy.

Thanks to Rusty for spotting this one, if the protocol module is not there
anymore (or is going away at that time) it is not supported, not busy.

With this the pppox module is protected by the networking core and
the pppox "core" protects modules for specific pppox protocols (pppoe,
for instance), while doing it removed some not needed struct sock
member initializations in pppoe_create that are done by sock_init_data.

. rename proto to pppox_protos, even being static this is too generic a name
. use rc as the name for result variables, just for consistency with other
  net sources

This is in preparation for having a proper net family module level modules
infrastructure, with the top level (af_pppox) doing the module refcounting
before calling any functions registered by the lower level protocol modules
(in this case just PPPOE for now).

. use switch/case alignment at the same column, 
  more common in the kernel sources
. remove outdated module refcounting comments
. have just one exit (return) in the ioctl functions
. use 'rc' for return variables, not ret or err, for
  consistency on naming.

Now the core networking infrastructure will (finally) do that for the net
protocol families, its just a matter of setting the ->owner field in the
registered struct net_proto_family to THIS_MODULE.

Adds an owner field to nf_hook_ops, and use it to hold the hook in place
for queued packets.
