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

Pull networking fixes from David Miller:
 "Several networking final fixes and tidies for the merge window:

   1) Changes during the merge window unintentionally took away the
      ability to build bluetooth modular, fix from Geert Uytterhoeven.

   2) Several phy_node reference count bug fixes from Uwe Kleine-König.

   3) Fix ucc_geth build failures, also from Uwe Kleine-König.

   4) Fix klog false positivies when netlink messages go to network
      taps, by properly resetting the network header.  Fix from Daniel
      Borkmann.

   5) Sizing estimate of VF netlink messages is too small, from Jiri
      Benc.

   6) New APM X-Gene SoC ethernet driver, from Iyappan Subramanian.

   7) VLAN untagging is erroneously dependent upon whether the VLAN
      module is loaded or not, but there are generic dependencies that
      matter wrt what can be expected as the SKB enters the stack.
      Make the basic untagging generic code, and do it unconditionally.
      From Vlad Yasevich.

   8) xen-netfront only has so many slots in it's transmit queue so
      linearize packets that have too many frags.  From Zoltan Kiss.

   9) Fix suspend/resume PHY handling in bcmgenet driver, from Florian
      Fainelli"
