addresses for -c and -B (#1157, #1180)
* Add get/set test_unit_format function declaration to iperf_api.h
* Auto adjustment of test-end condition for file transfers (-F), if no end
condition is set, it will automatically adjust it to file size in bytes
* Exit if idle time expires waiting for a connection in one-off mode (#1187,
#1197)
* Support zerocopy by reverse mode (#1204)
* Update help and manpage text for #1157, support bind device
* Consistently print target_bandwidth in JSON start section (#1177)
* Test bitrate added to JSON output (#1168)
* Remove fsync call after every write to receiving --file (#1176, #1159)
* Update documentation for -w (#1175)
* Fix for #952, different JSON object names for bidir reverse channel
* update to 3.10.1:
* Fixed a problem with autoconf scripts that made builds fail in some
environments (#1154 / #1155).

scripts.

* Fix a bug where some --reverse tests didn't terminate (#982 / #1054).
* Responsiveness of control connections is slightly improved (#1045 / #1046 /
#1063).
* The allowable clock skew when doing authentication between client and server
is now configurable with the new --time-skew-threshold (#1065 / #1070).
* Bitrate throttling using the -b option now works when a burst size is
specified (#1090).
* A bug with calculating CPU utilization has been fixed (#1076 / #1077).
* A --bind-dev option to support binding sockets to a given network interface
has been added to make iperf3 work better with multi-homed machines and/or
VRFs (#817 / #1089 / #1097).
* \--pidfile now works with --client mode (#1110).
* The server is now less likely to get stuck due to network errors (#1101,
#1125), controlled by the new --rcv-timeout option.
* Fixed a few bugs in termination conditions for byte or block-limited tests
(#1113, #1114, #1115).
* Added tcp_info.snd_wnd to JSON output (#1148).
* Some bugs with garbled JSON output have been fixed (#1086, #1118, #1143 /
#1146).
* Support for setting the IPv4 don't-fragment (DF) bit has been added with the
new --dont-fragment option (#1119).
* A failure with not being able to read the congestion control algorithm under
WSL1 has been fixed (#1061 / #1126).
* Error handling and error messages now make more sense in cases where sockets
were not successfully opened (#1129 / #1132 / #1136, #1135 / #1138, #1128 /

* It is now possible to use the API to set/get the congestion control
algorithm (#1036 / #1112).
* update to 3.9:
* A --timestamps flag has been added, which prepends a timestamp to each
output line. An optional argument to this flag, which is a format
specification to strftime(3), allows for custom timestamp formats (#909,
#1028).
* A --server-bitrate-limit flag has been added as a server-side command-line
argument. It allows a server to enforce a maximum throughput rate; client
connections that specify a higher bitrate or exceed this bitrate during a
test will be terminated. The bitrate is expressed in bits per second, with
an optional trailing slash and integer count that specifies an averaging
interval over which to enforce the limit (#999).
* A bug that caused increased CPU usage with the --bidir option has been fixed
(#1011).
* Fixed various minor memory leaks (#1023).
* update to 3.8.1
* Minor bugfixes and enhancements
* update to 3.7
* Support for simultaneous bidirectional tests with the --bidir flag
* Use POSIX standard clock_gettime(3) interface for timekeeping where
available
* Passwords for authentication can be provided via environment variable
* Specifying --repeating-payload and --reverse now works
* Failed authentication doesn't count for --one-off

* The delay for tearing down the control connection for the default timed
tests has been increased, to more gracefully handle high-delay paths
* Various improvements to the libiperf APIs
* Fixed build behavior when OpenSSL is absent
* Portability fixes
* update to 3.6
* A new --extra-data option can be used to fill in a user-defined string field
that appears in JSON output.
* A new --repeating-payload option makes iperf3 use a payload pattern similar
to that used by iperf2, which could help in recreating results that might be
affected by payload entropy (for example, compression).
* -B now works properly with SCTP tests.
* A compile fix for Solaris 10 was added.
* Some minor bug fixes for JSON output. In particular, warnings for debug
and/or verbose modes with --json output and a fix for JSON output on CentOS
6
* This maintenance release adds a -1 flag to make the iperf3 execute a single
test and exit, needed for an upcoming bwctl there is only one stream.
