Too many users have incorrectly assumed that ovs-controller is a necessary
or desirable part of an Open vSwitch deployment. This commit should fix
the problem by renaming it test-controller and removing it from the
default install and from packaging.

We have a controller that puts many rules with different metadata values
into the flow table, where metadata is used (by "resubmit"s) to distinguish
stages in a pipeline. Thus, any given flow only needs to be hashed into
classifier "cls_table"s that contain a match for the flow's metadata value.
This commit optimizes the classifier lookup by (probabilistically) skipping
the "cls_table"s that can't possibly match.
(The "metadata" referred to here is the OpenFlow 1.1+ "metadata" field,
which is a 64-bit field similar in purpose to the "registers" defined by
Open vSwitch.)
Previous versions of this patch, with earlier versions of the controller in
question, improved flow setup performance by about 19%.
Bug #14282.

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.

The "stress" library was introduced years ago. We intended at the time to
start using it to provoke errors in testing, to make sure that Open vSwitch
was resilient against those errors. The intention was good, but there were
few actual implementations of stress options, and the testing never
materialized.
Rather than adapt the stress library for thread safety, this seems like a
good opportunity to remove it, so this commit does so.

The underlying glibc interface is deprecated because the interface itself
is not thread-safe. That means that there's no way for a layer on top of
it to be thread-safe.

--protocols allows configuration of the versions
that may be used when establishing an OpenFlow connection.
The default is 'OpenFlow10' which is consistent with
the behaviour prior to this patch.
The useful values at this time are:
'OpenFlow10', 'OpenFlow12', 'OpenFlow13',
Values may be combined in a comma delimited list.
e.g.: --protocols 'OpenFlow10,OpenFlow12,OpenFlow13'

These commands will be useful in a future commit that makes multiple
bridges share a single backing datapath. The ovs-dpctl commands will
show information about the backing datapath, so it will be difficult to
determine which information belongs to which bridge. The new "dpif/*"
ovs-appctl commands return information about the bridge--regardless of
how the backing datapath is configured.

ovs-l3ping is similar to ovs-test, but the main difference
is that it does not require administrator to open firewall
holes for the XML/RPC control connection. This is achieved
by encapsulating the Control Connection over the L3 tunnel
itself.
This tool is not intended as a replacement for ovs-test,
because ovs-test covers much broader set of test cases.
Sample usage:
Node1: ovs-l3ping -s 192.168.122.236,10.1.1.1 -t gre
Node2: ovs-l3ping -c 192.168.122.220,10.1.1.2,10.1.1.1 -t gre

I've had a few complaints that ovs-vswitchd logs its coverage counters
at WARN level, but this is mainly wrong: ovs-vswitchd only logs coverage
counters at WARN level when the "coverage/log" command is used through
ovs-appctl. This was even documented.
The reason to log at such a high level was to make it fairly certain that
these messages specifically requested by the admin would not be filtered
out before making it to the log. But it's even better if the admin just
gets the coverage counters as a reply to the ovs-appctl command. So that
is what this commit does.
This commit also improves the documentation of the ovs-appctl command.

This tool will be a replacement for the current ovs-vlan-test
utility. Besides from connectivity issues it will also be able
to detect performance related issues in Open vSwitch setups.
Currently it uses UDP and TCP protocols for stressing.
Issue #6976
The version of groff on RHEL 5 doesn't include the .SY, .OP, or .YS macros
that ovs-benchmark.1 uses, so the manpage-check target fails on that
platform. This commit adds the groff definitions of those macros to a
file and includes it into ovs-benchmark.1.
I tested that this allows RHEL 5 to pass manpage-check.
