Pull networking fixes from David Miller:

 1) Fix double SKB free in bluetooth 6lowpan layer, from Jukka Rissanen.

 2) Fix receive checksum handling in enic driver, from Govindarajulu
    Varadarajan.

 3) Fix NAPI poll list corruption in virtio_net and caif_virtio, from
    Herbert Xu.  Also, add code to detect drivers that have this mistake
    in the future.

 4) Fix doorbell endianness handling in mlx4 driver, from Amir Vadai.

 5) Don't clobber IP6CB() before xfrm6_policy_check() is called in TCP
    input path,f rom Nicolas Dichtel.

 6) Fix MPLS action validation in openvswitch, from Pravin B Shelar.

 7) Fix double SKB free in vxlan driver, also from Pravin.

 8) When we scrub a packet, which happens when we are switching the
    context of the packet (namespace, etc.), we should reset the
    secmark.  From Thomas Graf.

 9) ->ndo_gso_check() needs to do more than return true/false, it also
    has to allow the driver to clear netdev feature bits in order for
    the caller to be able to proceed properly.  From Jesse Gross.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (62 commits)
  genetlink: A genl_bind() to an out-of-range multicast group should not WARN().

  bonding: change error message to debug message in __bond_release_one()
  genetlink: pass multicast bind/unbind to families
  netlink: call unbind when releasing socket
  netlink: update listeners directly when removing socket
  genetlink: pass only network namespace to genl_has_listeners()
  netlink: rename netlink_unbind() to netlink_undo_bind()
  net: Generalize ndo_gso_check to ndo_features_check
  net: incorrect use of init_completion fixup
