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"

+APM X-Gene SoC Ethernet nodes
+
+Ethernet nodes are defined to describe on-chip ethernet interfaces in
+APM X-Gene SoC.
+
+Required properties:
+- compatible: Should be "apm,xgene-enet"
+- reg: Address and length of the register set for the device. It contains the
+  information of registers in the same order as described by reg-names
+- reg-names: Should contain the register set names
+  - "enet_csr": Ethernet control and status register address space
+  - "ring_csr": Descriptor ring control and status register address space
+  - "ring_cmd": Descriptor ring command register address space
+- interrupts: Ethernet main interrupt
+- clocks: Reference to the clock entry.
+- local-mac-address: MAC address assigned to this device
+- phy-connection-type: Interface type between ethernet device and PHY device
+- phy-handle: Reference to a PHY node connected to this device
+
+- mdio: Device tree subnode with the following required properties:
+  - compatible: Must be "apm,xgene-mdio".
+  - #address-cells: Must be <1>.
+  - #size-cells: Must be <0>.
+
+  For the phy on the mdio bus, there must be a node with the following fields:
+  - compatible: PHY identifier.  Please refer ./phy.txt for the format.
+  - reg: The ID number for the phy.
+
+Optional properties:
+- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok".
+
+Example:
+	menetclk: menetclk {
+		compatible = "apm,xgene-device-clock";
+		clock-output-names = "menetclk";
+		status = "ok";
+	};
+
+	menet: ethernet@17020000 {
