Open vSwitch does not have native integration with Docker.
INSTALL.Docker explains how Open vSwitch can be integrated
with docker non-natively.
ovs-docker is a helper script to add network interfaces to
docker containers and to attach them as ports to OVS bridge.
This script can be further enhanced as we understand different
use cases.

Commit b2a0daa5bd (debian: Don't recreate bridges during manual restart.)
added a check on $RUNLEVEL to only create bridges and ports when the
system starts up. This fix does not work with systemd.
This commit uses a different approach to solve the same problem.

Cross-building openvswitch with debuild -aARCH (or equivalent) fails
because the target architecture is not getting passed to configure.
Thus binaries like ovs-appctl get built using the build host
architecture.

Until now, the OVS source tree has had a whole maze of header files that
make "#include <linux/openvswitch.h>" work OK regardless of platform, but
this confuses everyone new to the tree, at first glance, and is difficult
to understand at second glance too.
This commit renames include/linux/openvswitch.h to
datapath/linux/compat/include/linux/openvswitch.h without other change,
then modifies the userspace build to generate a header that makes sense in
portable Open vSwitch userspace from that header.
It then removes all the remaining include/linux/* files since they are now
unused.

Debian puts an extra "-Wformat" in the CFLAGS following OVS's own
"-Wformat -Wno-format-zero-length", which therefore overrides
-Wno-format-zero-length, so this commit adds an extra
-Wno-format-zero-length to avoid those false positives.

In the 'interfaces' file, if an admin adds the openvswitch interface
in 'auto', ifupdown will try to create OVS interfaces even before
openvswitch has started. In a case like that, assume that the admin
knows what he is doing and try to start openvswitch.
The negatives I see are
1. /usr is NFS mounted, in which case expect the admin
to mount it through initramfs.
2. syslog through network may not be accessible.
This is similar to what rhel does with commit 602453000e
(rhel: Automatically start openvswitch service before bringing an ovs
interface up or down)

Commit d473844693 (debian: Depend on 'kmod' instead of module-init-tools.)
switched from depending on module-init-tools to depending on kmod, which
is the new name of the appropriate package in Debian. Unfortunately,
while kmod is the right name for the latest Debian distribution, it doesn't
have that name in old distributions and thus breaks the build on those.
This commit should work OK in either case, since it allows both names.

There are a few structure definitions that is used from
these headers. So copy them from the netbsd repo.
The following changes have been made on top of it:
* The keyword "__packed" has been removed
from the headers as the corresponding Linux headers don't
do packing.
* #if BYTE_ORDER == 'X' macros have been replaced by CONSTANT_HTONx().
* code inside #ifdef _KERNEL has been deleted.
* code inside #ifdef ICMP6_STRINGS has been deleted.

Modifications on top of the version in NetBSD repo.
* Remove header files not available in Visual Studio.
* Remove some unwanted #defines.
* Add Open vSwitch specific header files like config.h, vlog.h, util.h
* Add the following #define's
define __UNCONST(a) ((void *)(unsigned long)(const void *)(a))
define _DIAGASSERT(q) ovs_assert(q)
define warnx VLOG_WARN
* Add extern declaration in getopt.h for optarg, optind.

Without these two iptables rules (one for UDP encapsulated IPsec and
another for direct IPsec), ovs-vswitchd would incorrectly conclude
that GRE packet belonged to a plain GRE tunnel instead of IPsec GRE
tunnel.

Libtool is now required as of commit 38b7a52b61 (openvswitch: Use libtool
and allow building shared libs).
It seems that a build requirement for Python slipped in a while back, for
generating ovs-vswitchd.conf.db.5, and no one complained, so we might as
well make it official. (That will let us simplify some bits of the build,
too, since they won't have to be conditional on Python anymore, so I'm all
in favor of this change.)

Open vSwitch bridges and ports can be configured through
the /etc/network/interfaces script. During system startup,
Open vSwitch startup script reads the interfaces file
and creates the bridges and ports. During system shutdown,
the bridges and ports are removed.
The same behavior also can occur with a manual 'restart' of
Open vswitch (ex: service openvswitch-switch restart).
This behavior has come across as undesirable in some cases.
ex: When some one manually creates interfaces through ovs-vsctl
and then restarts Open vSwitch, that interface is lost.
This commit changes the startup script such that, interfaces
are created and deleted through the startup script only when
RUNLEVEL environment variable is set. This behavior will be
consistent with the OVS RHEL ifcfg-* scripts too.

One option to compile Open vSwitch code in windows
is to use Visual c++ compiler.
From http://cccl.sourceforge.net/ :
"cccl is a wrapper around Microsoft Visual C++'s cl.exe
and link.exe. It converts Unix compiler parameters
into parameters understood by cl and link. cccl's main
use is for using Unix build processes with Microsoft
compilers. Using cccl in conjunction with ports of Unix
utilities, it is possible to build many Unix packages
using MSVC, without modifying the build process."
There are couple of forks of the project in the internet.
This particular piece is copied from:

These are auto-generated files, so it would be better not to keep them
inside Open vSwitch repository.
Behaviour before this patch was that if dot tool was not present on
the system, then ovs-vswitchd.conf.db.5 would have used pre-generated
vswitch.pic file that was already checked in the git repository. After
this patch ovs-vswitchd.conf.db.5 will simply not have a dot diagram,
if dot was not present at the time when Open vSwitch was built.

This python script summarizes ovs-dpctl dump-flows content by aggregating
the number of packets, total bytes and occurrence of the following fields:
- Datapath in_port
- Ethernet type
- Source and destination MAC addresses
- IP protocol
- Source and destination IPv4 addresses
- Source and destination IPv6 addresses
- UDP and TCP destination port
- Tunnel source and destination addresses
Testing included confirming both mega-flows and non-megaflows are
properly parsed. Bit masks are applied in the case of mega-flows
prior to aggregation. Test --script parameter which runs in
non-interactive mode. Tested syntax against python 2.4.3, 2.6 and 2.7.
Confirmed script passes pep8 and pylint run as:
pylint --disable=I0011 --include-id=y --reports=n
This tool has been added to these distribution:
- add ovs-dpctl-top to debian distribution
- add ovs-dpctl-top to rpm distribution.
- add ovs-dpctl-top to XenServer RPM.
