Compiled (64-bit) with GLib 2.24.1, with libpcap 1.0.0, with libz 1.2.3.3,
without POSIX capabilities, without libpcre, without SMI, without c-ares,
without ADNS, without Lua, without Python, with GnuTLS 2.8.5, with Gcrypt
1.4.4,
with MIT Kerberos, without GeoIP.

Running on Linux 2.6.32-34-generic, with libpcap version 1.0.0, with libz
1.2.3.3.

Built using gcc 4.4.3.

The field "octetsToNextHeader" (rtps2.sm.octetsToNextHeader) may be zero for
the last submessage in the message (see RTPS spec 2.1 sections 8.3.3.2.3 and
9.4.5.1.3).  However when the field is zero, wireshark does not correctly
dissect the submessage, and thinks there is an "unknown" submessage following
it.
