This involves copying the release notes through 3.0.11 into the
mainline release notes file, and then updating for changes on the
mainline that haven't appeared in any prior 3.0.x release. Not all
changes are listed.
We'll probably do a beta or two before a real 3.1.0 release.
Fix segfault in signal handler on the server if a signal arrives at the "wrong" time.
The change causes the signal handler to use a stack context whose lifetime should be valid the entire time the signal handler is active.
Fixes#257, #258.
The case where we should have been binding the client sockets to
ephemeral ports at a specific address for parallel tests was broken.
Fixes#239

Solaris implements an (older?) version of the API for SCTP_MAXSEG,
which takes an integer argument rather than a struct sctp_assoc_val.
We need to test for that and handle it appropriately. There are some
signs it doesn't even work correctly if we do this, so quietly ignore
errors that happen if the OS complains it's unsupported.
Also, Solaris doesn't support SCTP_DISABLE_FRAGMENTS even though it
defines the preprocessor symbol for this. Rather than aborting when
we try to unsuccessfully unset this option, just ignore the error.
Lightly tested with SCTP over IPv6 on localhost.
Contains an alternate implementation of previously-submitted patches
to set the maximum segment size and no-delay options.
As a result of this change, SCTP functionality on Linux will generally
require the libsctp library (on CentOS and similar distributions this
is provided by the lksctp-tools RPM).
Part of #131.

The problem is that the new byte-ordering macros adopted on master
don't support CentOS 5 because they assumed that any Linux system had
endian(3) support. CentOS 6 (and presumably newer) do, but CentOS 5
doesn't.
So instead we only do glibc endian(3) support if we're on a system
with glibc 2.9 or higher (which is when this functionality was
introduced).
For any other platform that we don't detect (which now includes older
glibc such as CentOS 5), bring back our homebrewed htonll and ntohll
implementation from iperf 3.0.x.
Fixes#224.
Primarily useful for bwctl integration, this is enabled with the -1
and/or --one-off flags.
Fixes#230, based on a patch by @i2aaron.

Add timeout to the UDP socket. Without it client would block infinitely
if creating a control connection succeeds, but UDP packets are dropped
by firewall.
size.
This appears to be necessary on some long, high-bandwidth paths
to get sane results, either by reducing packet loss or by somehow
allowing the sending host of a test to go faster.
Fixes#219.
