iperf3 with tls support
cfe8c5fb47
(Formerly it was just accepting IPv6.) The problem here was that FreeBSD by default wasn't allowing IPv4 mapped addresses on IPv6 sockets, whereas other platforms (specifically Linux and OS X) both do permit this. We tried to turn on mapped addresses via a setsockopt(IPV6_V6ONLY) call, but this call was broken because the level argument was incorrect. We didn't know about this because we never checked the return value. Fix this by providing the correct argument to setsockopt(). Add some error checking to this and one other setsockopt() call, so we at least don't fail silently in similar situations. Issue: 126 (FreeBSD: iperf3 -s only accepts IPv6 connections) |

= Summary =
iperf3 is a tool for measuring achievable bandwidth on IP networks.
iperf3 is NOT backwards compatible with the original iperf.
Supported platforms:
* Linux
* FreeBSD
* Mac OSX
= Building iperf3 =
== Prerequisites: ==
* libuuid: this is not installed by default for Debian/Ubuntu Systems
to install: apt-get install uuid-dev
== Building ==
./configure; make; make install
== Latest version ==
To check out the most recent code, do: hg clone http://code.google.com/p/iperf/
== Bug Reports ==
Before submitting a bug report, try checking out the latest version of the code, and confirm that its not
already fixed. Then submit to: https://code.google.com/p/iperf/issues/list
For more information see: http://code.google.com/p/iperf/
== Changes from iperf 2.x ==
New options:
-V, --verbose more detailed output than before
-J, --json output in JSON format
-Z, --zerocopy use a 'zero copy' sendfile() method of sending data
-O, --omit N omit the first n seconds (to ignore slowstart)
-T, --title str prefix every output line with this string
-F, --file name xmit/recv the specified file
-A, --affinity n/n,m set CPU affinity
Depricated options:
Plan to add for the next release:
-D, --daemon run the server as a daemon
Not planning to support. If you really miss these options, please submit a request in the issue tracker
-d, --dualtest Do a bidirectional test simultaneously
-r, --tradeoff Do a bidirectional test individually
-N, --nodelay set TCP no delay, disabling Nagle's Algorithm
-T, --ttl time-to-live, for multicast (default 1)
-Z, --linux-congestion <algo> set TCP congestion control algorithm (Linux only)
-x, --reportexclude [CDMSV] exclude C(connection) D(data) M(multicast) S(settings) V(server) reports
-y, --reportstyle C report as a Comma-Separated Values
Also deprecated is the ability to set the options via environment variables.
For sample command line usage, see:

Using the default options, iperf is meant to show typical well designed application performance.
'Typical well designed application' means avoiding artificial enhancements that work only for testing
(such as splice()'ing the data to /dev/null). iperf does also have flags for 'extreme best case'
optimizations but they must be explicitly activated.
These flags include:
-Z, --zerocopy use a 'zero copy' sendfile() method of sending data
-A, --affinity n/n,m set CPU affinity
