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

Pull networking fixes from David Miller:

 1) Avoid negative netdev refcount in error flow of xfrm state add, from
    Aviad Yehezkel.

 2) Fix tcpdump decoding of IPSEC decap'd frames by filling in the
    ethernet header protocol field in xfrm{4,6}_mode_tunnel_input().
    From Yossi Kuperman.

 3) Fix a syzbot triggered skb_under_panic in pppoe having to do with
    failing to allocate an appropriate amount of headroom. From
    Guillaume Nault.

 4) Fix memory leak in vmxnet3 driver, from Neil Horman.

 5) Cure out-of-bounds packet memory access in em_nbyte EMATCH module,
    from Wolfgang Bumiller.

 6) Restrict what kinds of sockets can be bound to the KCM multiplexer
    and also disallow when another layer has attached to the socket and
    made use of sk_user_data. From Tom Herbert.

 7) Fix use before init of IOTLB in vhost code, from Jason Wang.

 8) Correct STACR register write bit definition in IBM emac driver, from
    Ivan Mikhaylov.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  net/ibm/emac: wrong bit is used for STA control register write
  net/ibm/emac: add 8192 rx/tx fifo size
  vhost: do not try to access device IOTLB when not initialized
  vhost: use mutex_lock_nested() in vhost_dev_lock_vqs()
  i40e: flower: check if TC offload is enabled on a netdev
  qed: Free reserved MR tid
  qed: Remove reserveration of dpi for kernel
  kcm: Check if sk_user_data already set in kcm_attach
  kcm: Only allow TCP sockets to be attached to a KCM mux
  net: sched: fix TCF_LAYER_LINK case in tcf_get_base_ptr
  net: sched: em_nbyte: don't add the data offset twice
  mlxsw: spectrum_router: Don't log an error on missing neighbor
  vmxnet3: repair memory leak
  ipv6: Fix getsockopt() for sockets with default IPV6_AUTOFLOWLABEL
  pppoe: take ->needed_headroom of lower device into account on xmit
  xfrm: fix boolean assignment in xfrm_get_type_offload
  xfrm: Fix eth_hdr(skb)->h_proto to reflect inner IP version
  xfrm: fix error flow in case of add state fails
  xfrm: Add SA to hardware at the end of xfrm_state_construct()
