- New Config option to configure the sequence of frames using UDP
- an Info will be added, if the SCM UDID is not configured or if it is wrongly
configured, so that the user can act on it.
- SCM UDID will only be printed if configured correctly, if not a warning will
be added to inform, that the first byte for the UDID will be assumed to be 00
- UDP dissection can enforce the number of sub-package the dissection should
assume
- SSDO: isRequest is determined by it's field not by the message id
- SSDO: Unused code for SNMT Reset Guarding SCM has been removed
- SNMT: error_group and error_code for SN_FAIL have not been dissected
correctly
- Sercos III: bug != instead of ==, is fixed
- dissect_opensafety_udp renamed to dissect_opensafety_udpdata, because of
future dissector called opensafety_udp which will handle transport of
openSAFETY data over UDP
- dissect_opensafety_udpdata enhanced to determine the index of the given frame
in the package. Needed for correct assembly of COL_INFO
- Added heuristic dissector hook for opensafety_udp dissector. The dissector
will be submitted to this list at a future point
- Enhanced description of the dissector to reflect it's capabilities
- Reworked the description for the config options to be more understandable

> WTAP_MAX_PACKET_SIZE, either that should be caught above the
per-file-type layer in Wiretap or should be handled by the caller.
We've recently fixed at least one problem with reported lengths > 2^31 -
1 (by clamping the length to 2^31 - 1), so let's just remove the check
from the pcap-NG reader, to squelch some complaints we're getting from
the buildbot (bug 6673 and its duplicates).
(The pcap reader uses it to cope with some of the botched libpcap
formats that changed the per-packet header without changing the magic
number; I'll look at trying to preserve those heuristics while still
allowing reported lengths > WTAP_MAX_PACKET_SIZE.)

Essentially: generate tvbuffs as needed; don't save them for later reuse
with the result they are never freed.
Also:
- move a struct from packet-nfs.h to packet-nfs.c since it's only used locally;
- reformat some long lines.

call, and using ep_address_to_str(), so it can handle any address type,
including AT_NONE if the source address isn't available.

protocol.
Point to an HP document o the protocol, and discuss the two ways to hook
up the dissector.
Don't bother checking the destination address - either the OUI/PID
suffices, or the MAC address is both necessary and, presumably,
sufficient and we need to introduce a heuristic dissector table for SNAP
frames. What's more, there's no guarantee that the destination address
is a MAC address - it might be absent, e.g. because you're capturing on
the Linux "any" device and are getting the "Linux cooked" header, with
only a destination address.
Don't put the source address into the Info column - it's already in the
source column *if* it exists (which it might not, for packets captured
from the "any" device and sent by the machine doing the capturing).

we're given null pointers.
Put in comments clarifying that some routines intentionally do *not*
null terminate the strings they produce.

dissector bug exception in cases where a null pointer was passed, as
those really *are* dissector bugs (and I have a fix for the bug in
question in the HP Teaming heartbeat dissector, which I'll be checking
in later).

Actual problem:
A REAL_DATA tvbuff wasn't being added to the "data_sources"
for a frame. When displaying the frame, when a field referencing the tvb was selected
for display there was no 'hex bytes' tab for the field and so bytes ended up being
highlighted in the currently displayed hex bytes tab (thus highlighting bytes in a pane
not related to the field).
Consider: Add some code in field creation (proto_tree_add...) to at least warn if
a field is being created using a tvb whose data_source is not in the
data_sources list for the frame ?
