Only send the cleanup messages when the socket is not in a front state.
This fixes a bug where in case of the SUT being a server was sent
a TCP RST with wildcard addresses and ports.

No functional change.

On FreeBSD python is installed in /usr/local. So use that as the
default.

association.

For FreeBSD use ioctl() to set the speed and mtu of the tun
interface instead of the Linux specific ethtool for the speed.
Also ensure that you can set the MTU to the default value in
case it is configured to a different one.
On non-FreeBSD platforms restore the old behaviour.
This fixes https://github.com/nplab/packetdrill/issues/17

This patch add support for the PAD chunk and PAD parameter defined
in https://tools.ietf.org/html/rfc4820
This fixes https://github.com/nplab/packetdrill/issues/16

This patch adds support for the SCTP parameters defined in RFC 4960.
While there, make the syntax more consistent and make sure that
the packet printing is in line with the syntax being used.
This fixes https://github.com/nplab/packetdrill/issues/6

If the interface MTU was previously set to a non-default value
and in a later run should be set to the default value, it was
not set correctly. With this patch, the MTU is always set.

Move invariant code out of a loop.

When outbound HEARTBEAT chunks are observed, inject the appropriate
HEARTBEAT-ACK chunk when scripted.
While there, plug a memory leak and rename a variable for consistency.
This fixes https://github.com/nplab/packetdrill/issues/11

This test is used to test the injecting of correct HEARTBEAT-ACK
chunks for outbound HEARTBEAT chunks.

Put in a missing ',' between the flags and error causes when
printing ABORT[] and ERROR[] chunks if both are available.

This disables the IPv6 payload length check for now, similar to the
hack for IPv4. Will add a fix later.

linux/version.h. At least not on Rasbian. So take out the last
change and just try to set TUN_F_UFO and ignore if it worked
or not.
This allows to run packetdrill on a Raspberry Pi running Rasbian.

Current limitations:
* Chunk parameters are not yet supported.
* Error causes are not yet supported.
* Chunks can't be bundled with COOKIE-ECHO chunks.
* Chunk flags are not supported.
* Chunk lengths are not supported.
* Gap reports and duplicate TSNs are not supported for SACK chunks.
* SCTP related ICMP messages are not supported.
This version is only tested in a limited way, only on FreeBSD and
only in local mode.
