Update the necessary make and configure files to remove the Linux
datapath and then remove the datapath.
Move datapath/linux/compat/include/linux/openvswitch.h to
include/linux/openvswitch.h because it is needed to generate header
files used by the userspace switch.
Also remove references to the Linux datapath from auxiliary files
and utilities since it is no longer supported.

The Stateless TCP Tunnel (STT) protocol encapsulates traffic in
IPv4/TCP packets.
STT uses TCP segmentation offload available in most of NIC. On
packet xmit STT driver appends STT header along with TCP header
to the packet. For GSO packet GSO parameters are set according
to tunnel configuration and packet is handed over to networking
stack. This allows use of segmentation offload available in NICs
The protocol is documented at

This resolves the differences between the OVS Geneve implementation
and the upstream kernel, particularly in the area of the split
between vport-geneve.c and the generic Geneve data plane.

Upstream commit:
udp: Generic functions to set checksum
Added udp_set_csum and udp6_set_csum functions to set UDP checksums
in packets. These are for simple UDP packets such as those that might
be created in UDP tunnels.

Upstream commit:
udp: Add udp_sock_create for UDP tunnels to open listener socket
Added udp_tunnel.c which can contain some common functions for UDP
tunnels. The first function in this is udp_sock_create which is used
to open the listener port for a UDP tunnel.

LISP is an experimental layer 3 tunneling protocol, described in RFC
6830. This patch adds support for LISP tunneling. Since LISP
encapsulated packets do not carry an Ethernet header, it is removed
before encapsulation, and added with hardcoded source and destination
MAC addresses after decapsulation. The harcoded MAC chosen for this
purpose is the locally administered address 02:00:00:00:00:00. Flow
actions can be used to rewrite this MAC for correct reception. As such,
this patch is intended to be used for static network configurations, or
with a LISP capable controller.

The CAPWAP implementation is just the encapsulation format and
therefore really not the full protocol. While there were some
uses of it (primarily hardware support and UDP transport). But
these are most likely better provided by VXLAN.
Following patch removes CAPWAP tunneling support.

datapath changes. We have decided to remove it as it is

Add support for VXLAN tunnels to Open vSwitch. Add support
for setting the destination UDP port on a per-port basis.
This is done by adding a "dst_port" parameter to the port
configuration. This is only applicable currently to VXLAN
tunnels.
Please note this currently does not implement any sort of multicast
learning. With this patch, VXLAN tunnels must be configured similar
to GRE tunnels (e.g. point to point). A subsequent patch will implement
a VXLAN control plane in userspace to handle multicast learning.
This patch set is based on one posted by Ben Pfaff on Oct. 12, 2011
to the ovs-dev mailing list:
http://openvswitch.org/pipermail/dev/2011-October/012051.html
The patch has been maintained, updated, and freshened by me and a
version of it is available at the following github repository:
https://github.com/mestery/ovs-vxlan/tree/vxlan
I've tested this patch with multiple VXLAN tunnels between hosts
using different UDP port numbers. Performance is on par (though
slightly faster) than comparable GRE tunnels.
See the following IETF draft for additional information about VXLAN:

brc_sysfs_* was renamed to dp_sysfs_* a few years ago

flex_arrays didn't exist at all until 2.6.30, weren't exported to modules
until 2.6.38, and performed poorly until 3.0, so this backports the
functionality to older kernels.
