Pull networking changes from David Miller:

 1) GRE now works over ipv6, from Dmitry Kozlov.

 2) Make SCTP more network namespace aware, from Eric Biederman.

 3) TEAM driver now works with non-ethernet devices, from Jiri Pirko.

 4) Make openvswitch network namespace aware, from Pravin B Shelar.

 5) IPV6 NAT implementation, from Patrick McHardy.

 6) Server side support for TCP Fast Open, from Jerry Chu and others.

 7) Packet BPF filter supports MOD and XOR, from Eric Dumazet and Daniel
    Borkmann.

 8) Increate the loopback default MTU to 64K, from Eric Dumazet.

 9) Use a per-task rather than per-socket page fragment allocator for
    outgoing networking traffic.  This benefits processes that have very
    many mostly idle sockets, which is quite common.

    From Eric Dumazet.

10) Use up to 32K for page fragment allocations, with fallbacks to
    smaller sizes when higher order page allocations fail.  Benefits are
    a) less segments for driver to process b) less calls to page
    allocator c) less waste of space.

    From Eric Dumazet.

11) Allow GRO to be used on GRE tunnels, from Eric Dumazet.

12) VXLAN device driver, one way to handle VLAN issues such as the
    limitation of 4096 VLAN IDs yet still have some level of isolation.
    From Stephen Hemminger.

13) As usual there is a large boatload of driver changes, with the scale
    perhaps tilted towards the wireless side this time around.

Fix up various fairly trivial conflicts, mostly caused by the user
namespace changes.

Bosch C_CAN/D_CAN controller Device Tree Bindings
-------------------------------------------------
Required properties:
- compatible : Should be "bosch,c_can" for C_CAN controllers and
"bosch,d_can" for D_CAN controllers.
- reg : physical base address and size of the C_CAN/D_CAN
registers map
- interrupts : property with a value describing the interrupt
number
Optional properties:

Note: "ti,hwmods" field is used to fetch the base address and irq
resources from TI, omap hwmod data base during device registration.
Future plan is to migrate hwmod data base contents into device tree
blob so that, all the required data will be used from device tree dts
file.
Example:
Step1: SoC common .dtsi file
dcan1: d_can@481d0000 {

Properties for an MDIO bus multiplexer controlled by a memory-mapped device
This is a special case of a MDIO bus multiplexer. A memory-mapped device,
like an FPGA, is used to control which child bus is connected. The mdio-mux
node must be a child of the memory-mapped device. The driver currently only
supports devices with eight-bit registers.
Required properties in addition to the generic multiplexer properties:
- compatible : string, must contain "mdio-mux-mmioreg"
- reg : integer, contains the offset of the register that controls the bus
multiplexer. The size field in the 'reg' property is the size of
register, and must therefore be 1.
- mux-mask : integer, contains an eight-bit mask that specifies which
bits in the register control the actual bus multiplexer. The
'reg' property of each child mdio-mux node must be constrained by
this mask.
Example:
The FPGA node defines a memory-mapped FPGA with a register space of 0x30 bytes.
For the "EMI2" MDIO bus, register 9 (BRDCFG1) controls the mux on that bus.
A bitmask of 0x6 means that bits 1 and 2 (bit 0 is lsb) are the bits on
BRDCFG1 that control the actual mux.

Virtual eXtensible Local Area Networking documentation
======================================================
The VXLAN protocol is a tunnelling protocol that is designed to
solve the problem of limited number of available VLAN's (4096).
With VXLAN identifier is expanded to 24 bits.
It is a draft RFC standard, that is implemented by Cisco Nexus,
Vmware and Brocade. The protocol runs over UDP using a single
destination port (still not standardized by IANA).
This document describes the Linux kernel tunnel device,
there is also an implantation of VXLAN for Openvswitch.
Unlike most tunnels, a VXLAN is a 1 to N network, not just point
to point. A VXLAN device can either dynamically learn the IP address
of the other end, in a manner similar to a learning bridge, or the
forwarding entries can be configured statically.
The management of vxlan is done in a similar fashion to it's
too closest neighbors GRE and VLAN. Configuring VXLAN requires
the version of iproute2 that matches the kernel release
where VXLAN was first merged upstream.
1. Create vxlan device
# ip li add vxlan0 type vxlan id 42 group 239.1.1.1 dev eth1
This creates a new device (vxlan0). The device uses the
the multicast group 239.1.1.1 over eth1 to handle packets where
no entry is in the forwarding table.
2. Delete vxlan device
# ip link delete vxlan0
3. Show vxlan info
# ip -d show vxlan0
It is possible to create, destroy and display the vxlan
forwarding table using the new bridge command.
1. Create forwarding table entry
# bridge fdb add to 00:17:42:8a:b4:05 dst 192.19.0.2 dev vxlan0
2. Delete forwarding table entry
# bridge fdb delete 00:17:42:8a:b4:05
3. Show forwarding table
# bridge fdb show dev vxlan0
