Pull networking fixes from David Miller:
 "A moderately sized pile of fixes, some specifically for merge window
  introduced regressions although others are for longer standing items
  and have been queued up for -stable.

  I'm kind of tired of all the RDS protocol bugs over the years, to be
  honest, it's way out of proportion to the number of people who
  actually use it.

   1) Fix missing range initialization in netfilter IPSET, from Jozsef
      Kadlecsik.

   2) ieee80211_local-&gt;tim_lock needs to use BH disabling, from Johannes
      Berg.

   3) Fix DMA syncing in SFC driver, from Ben Hutchings.

      Pirko.

   5) Missing usb_free_urb in ISDN Hisax driver, from Marina Makienko.

   6) Fix UDP checksumming in bnx2x driver for 57710 and 57711 chips,
      fix from Dmitry Kravkov.

   7) Missing cfgspace_lock initialization in BCMA driver.

   8) Validate parameter size for SCTP assoc stats getsockopt(), from
      Guenter Roeck.

  10) Fix jumbo frame handling in r8169, from Francois Romieu.

  11) Fix phy_device memory leak, from Petr Malat.

  12) Omit trailing FCS from frames received in BGMAC driver, from Hauke
      Mehrtens.

  13) Missing socket refcount release in L2TP, from Guillaume Nault.

  14) sctp_endpoint_init should respect passed in gfp_t, rather than use
      GFP_KERNEL unconditionally.  From Dan Carpenter.

  15) Add AISX AX88179 USB driver, from Freddy Xin.

  16) Remove MAINTAINERS entries for drivers deleted during the merge
      window, from Cesar Eduardo Barros.

  17) RDS protocol can try to allocate huge amounts of memory, check
      that the user's request length makes sense, from Cong Wang.

  18) SCTP should use the provided KMALLOC_MAX_SIZE instead of it's own,
      bogus, definition.  From Cong Wang.

  19) Fix deadlocks in FEC driver by moving TX reclaim into NAPI poll,
      from Frank Li.  Also, fix a build error introduced in the merge
      window.

Apparently overwrites the sdata pointer with non-valid data in

Commit 6c17b77b67587b9f9e3070fb89fe98cef3187131 (mac80211: Fix tx queue
handling during scans) contains a bug that causes off-channel frames to
get queued when they should be handed down to the driver for transmit.
Prevent this from happening.

Unicast frame with unknown forwarding information always trigger
the path discovery assuming destination is always located inside the
MBSS. This patch allows the forwarding to look for mesh gate if path

The ieee80211_beacon_add_tim() function might be called
by drivers with BHs enabled, which causes a potential
deadlock if TX happens at the same time and attempts to
lock the tim_lock as well. Use spin_lock_bh to fix it.

There's various code with strange indentation,
questionable loop and locking constructs, etc.

The bigger change is moving the "sdata" argument
to the first argument of all functions, like all
other mac80211 functions that have one.

Previously, the entire mesh beacon would be generated each
time the beacon timer fired. Instead generate a beacon
head and tail (so the TIM can easily be inserted when mesh
power save is on) when starting a mesh or the MBSS
parameters change.

Also add a mutex for protecting beacon updates and
preventing leaks.

There's no need to use _irqsave() as the lock
is never used in interrupt context.

This also fixes a problem in the iwlwifi MVM
driver that calls spin_unlock_bh() within its
set_tim() callback.
