Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net

Pull more networking updates from David Miller:
 "Ok, everything from here on out will be bug fixes."

1) One final sync of wireless and bluetooth stuff from John Linville.
   These changes have all been in his tree for more than a week, and
   therefore have had the necessary -next exposure.  John was just away
   on a trip and didn't have a change to send the pull request until a
   day or two ago.

2) Put back some defines in user exposed header file areas that were
   removed during the tokenring purge.  From Stephen Hemminger and Paul
   Gortmaker.

3) A bug fix for UDP hash table allocation got lost in the pile due to
   one of those "you got it..  no I've got it.." situations.  :-)

   From Tim Bird.

4) SKB coalescing in TCP needs to have stricter checks, otherwise we'll
   try to coalesce overlapping frags and crash.  Fix from Eric Dumazet.

5) RCU routing table lookups can race with free_fib_info(), causing
   crashes when we deref the device pointers in the route.  Fix by
   releasing the net device in the RCU callback.  From Yanmin Zhang.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (293 commits)
  tcp: take care of overlaps in tcp_try_coalesce()
  ipv4: fix the rcu race between free_fib_info and ip_route_output_slow
