Pull networking fixes from David Miller:
 1) Name string overrun fix in gianfar driver from Joe Perches.

 2) VHOST bug fixes from Michael S. Tsirkin and Nadav Har'El

 3) Fix dependencies on xt_LOG netfilter module, from Pablo Neira Ayuso.

 4) Fix RCU locking in xt_CT, also from Pablo Neira Ayuso.

 5) Add a parameter to skb_add_rx_frag() so we can fix the truesize
    adjustments in the drivers that use it.  The individual drivers
    aren't fixed by this commit, but will be dealt with using follow-on
    commits.  From Eric Dumazet.

 6) Add some device IDs to qmi_wwan driver, from Andrew Bird.

 7) Fix a potential rcu_read_lock() imbalancein rt6_fill_node().  From
    Eric Dumazet.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net:
  net: fix a potential rcu_read_lock() imbalance in rt6_fill_node()
  net: add a truesize parameter to skb_add_rx_frag()
  gianfar: Fix possible overrun and simplify interrupt name field creation
  USB: qmi_wwan: Add ZTE (Vodafone) K3570-Z and K3571-Z net interfaces
  USB: option: Ignore ZTE (Vodafone) K3570/71 net interfaces
  USB: qmi_wwan: Add ZTE (Vodafone) K3565-Z and K4505-Z net interfaces
  qlcnic: Bug fix for LRO
  netfilter: nf_conntrack: permanently attach timeout policy to conntrack
  netfilter: xt_CT: fix assignation of the generic protocol tracker
  netfilter: xt_CT: missing rcu_read_lock section in timeout assignment
  netfilter: cttimeout: fix dependency with l4protocol conntrack module
  netfilter: xt_LOG: use CONFIG_IP6_NF_IPTABLES instead of CONFIG_IPV6
  vhost: fix release path lockdep checks
  vhost: don't forget to schedule()
  tools/virtio: stub out strong barriers
  tools/virtio: add linux/hrtimer.h stub
  tools/virtio: add linux/module.h stub
