With this PF_LLC is tightly integrated with the core and that is a
good thing 8)

. kill llc_ui_opt, the only non-duplicated bit is struct sockaddr_llc
  and this now lives in llc_opt
. remove debug code from llc_sk_alloc/free (previously llc_sock_alloc/free)
. the skbs allocated for event processing don't need to have any payload
  at all, just the skb->cb is enough, so remove the bogus 1 from alloc_skb
  calls
. llc_conn_disc put on death row
. llc_process_tmr_ev callers have to hold the socket lock
. the request functions in llc_if.c doesn't hold the socket lock anymore
  its up to its callers on the socket layer (llc_sock.c)
. llc_sk_alloc now receives a priority for sk_alloc call and is the
  only way to alloc a new sock (from llc_mac and llc_sock, bottom and top)
. added the traditional struct sock REFCNT_DEBUG support for llc
. llc_sock was simplified and is on the zen route to cleanliness, wait for
  the next patches, it'll shrink a lot when I zap all the crap (as in
  not needed) list handling, using the existing list maintained in
  struct llc_sap for that, probably splitting it in two, one for listening
  sockets and other for (being) established ones.  Ah, and the sap->ind
  and sap->req and friends will die.
