      ====================
      mlx4_en fixes for 4.7-rc
      
      This small patchset includes two small fixes for mlx4_en driver.
      
      One allows a clean shutdown even when clients do not release their
      netdev reference.
      The other adds error return values to the VLAN VID add/kill functions.

      net/mlx4_en: Avoid unregister_netdev at shutdown flow · 9d769311
      Eran Ben Elisha authored
      This allows a clean shutdown, even if some netdev clients do not
      release their reference from this netdev. It is enough to release
      the HW resources only as the kernel is shutting down.

      tipc: unclone unbundled buffers before forwarding · 27777daa
      Jon Paul Maloy authored
      When extracting an individual message from a received "bundle" buffer,
      we just create a clone of the base buffer, and adjust it to point into
      the right position of the linearized data area of the latter. This works
      well for regular message reception, but during periods of extremely high
      load it may happen that an extracted buffer, e.g, a connection probe, is
      reversed and forwarded through an external interface while the preceding
      extracted message is still unhandled. When this happens, the header or
      data area of the preceding message will be partially overwritten by a
      MAC header, leading to unpredicatable consequences, such as a link
      reset.
      
      We now fix this by ensuring that the msg_reverse() function never
      returns a cloned buffer, and that the returned buffer always contains
      sufficient valid head and tail room to be forwarded.

      It is caused by a missing free in the ->release path. So fix it by
      providing seq_release_net as the ->release method.

      team: Fix possible deadlock during team enslave · 942f64c4
      Ido Schimmel authored
      Both dev_uc_sync_multiple() and dev_mc_sync_multiple() require the
      source device to be locked by netif_addr_lock_bh(), but this is missing
      in team's enslave function, so add it.
      
      This fixes the following lockdep warning:
      
      Possible interrupt unsafe locking scenario:
      
              CPU0                    CPU1
              ----                    ----
         lock(_xmit_ETHER/1);
                                      local_irq_disable();
                                      lock(&(&mc->mca_lock)->rlock);
                                      lock(&team_netdev_addr_lock_key);
         <Interrupt>
           lock(&(&mc->mca_lock)->rlock);

      ====================
      pull-request: can 2016-06-20
      
      this is a pull request of 3 patches for the upcoming linux-4.7 release.
      
      The first patch is by Thor Thayer for the c_can/d_can driver. It fixes the
      registar access on Altera Cyclone devices, which caused CAN frames to have 0x0
      in the first two bytes incorrectly. Wolfgang Grandegger's patch for the at91
      driver fixes a hanging driver under high bus load situations. A patch for the
      gs_usb driver by Maximilian Schneider adds support for the bytewerk.org
      candleLight interface.
