Pull networking fixes from David Miller:
 "Bug fixes galore, mostly in drivers as is often the case:

  1) USB gadget and cdc_eem drivers need adjustments to their frame size
     lengths in order to handle VLANs correctly.  From Ian Coolidge.

  2) TIPC and several network drivers erroneously call tasklet_disable
     before tasklet_kill, fix from Xiaotian Feng.

  3) r8169 driver needs to apply the WOL suspend quirk to more chipsets,
     fix from Cyril Brulebois.

  4) Fix multicast filters on RTL_GIGA_MAC_VER_35 r8169 chips, from
     Nathan Walp.

  5) FDB netlink dumps should use RTM_NEWNEIGH as the message type, not
     zero.  From John Fastabend.

  6) Fix smsc95xx tx checksum offload on big-endian, from Steve
     Glendinning.

  7) __inet_diag_dump() needs to repsect and report the error value
     returned from inet_diag_lock_handler() rather than ignore it.
     Otherwise if an inet diag handler is not available for a particular
     protocol, we essentially report success instead of giving an error
     indication.  Fix from Cyrill Gorcunov.

  8) When the QFQ packet scheduler sees TSO/GSO packets it does not
     handle things properly, and in fact ends up corrupting it's
     datastructures as well as mis-schedule packets.  Fix from Paolo
     Valente.

  9) Fix oopser in skb_loop_sk(), from Eric Leblond.

  10) CXGB4 passes partially uninitialized datastructures in to FW
      commands, fix from Vipul Pandya.

  11) When we send unsolicited ipv6 neighbour advertisements, we should
      send them to the link-local allnodes multicast address, as per
      RFC4861.  Fix from Hannes Frederic Sowa.

  12) There is some kind of bug in the usbnet's kevent deferral
      mechanism, but more immediately when it triggers an uncontrolled
      stream of kernel messages spam the log.  Rate limit the error log
      message triggered when this problem occurs, as sending thousands
      of error messages into the kernel log doesn't help matters at all,
      and in fact makes further diagnosis more difficult.

      From Steve Glendinning.

  13) Fix gianfar restore from hibernation, from Wang Dongsheng.

  14) The netlink message attribute sizes are wrong in the ipv6 GRE
      driver, it was using the size of ipv4 addresses instead of ipv6
      ones :-) Fix from Nicolas Dichtel."

- * XXX we should make sure that slot becomes less than 32.

- * roundedS is always cl->S rounded on grp->slot_shift bits.
+ * If the weight and lmax (max_pkt_size) of the classes do not change,
+ * then QFQ guarantees that the slot index is never higher than
+ * 2 + ((1<<QFQ_MTU_SHIFT)/QFQ_MIN_LMAX) * (QFQ_MAX_WEIGHT/QFQ_MAX_WSUM).
+ *
+ * With the current values of the above constants, the index is
+ * then guaranteed to never be higher than 2 + 256 * (1 / 16) = 18.
+ *
+ * When the weight of a class is increased or the lmax of the class is
+ * decreased, a new class with smaller slot size may happen to be
+ * activated. The activation of this class should be properly delayed
+ * to when the service of the class has finished in the ideal system
+ * tracked by QFQ. If the activation of the class is not delayed to
+ * this reference time instant, then this class may be unjustly served
+ * before other classes waiting for service. This may cause
+ * (unfrequently) the above bound to the slot index to be violated for
+ * some of these unlucky classes.
+ *
+ * Instead of delaying the activation of the new class, which is quite
+ * complex, the following inaccurate but simple solution is used: if
+ * the slot index is higher than QFQ_MAX_SLOTS-2, then the timestamps
+ * of the class are shifted backward so as to let the slot index
+ * become equal to QFQ_MAX_SLOTS-2. This threshold is used because, if
+ * the slot index is above it, then the data structure implementing
+ * the bucket list either gets immediately corrupted or may get
+ * corrupted on a possible next packet arrival that causes the start
+ * time of the group to be shifted backward.
