Add support for the Cisco MetaData (0x8909) ethertype.
From me:
Don't try to register the "eth.type" abbreviation; use "cmd.type" instead.
Add SVN id.
Clean up trailing white space and fix up some indentation.
Don't declare a variable static that need not be.

was done using textual search+replace, not anything syntax-aware, so presumably
it got most comments as well (except where there were typos).
Use a consistent coding style, and make proper use of the WS_DLL_* defines.
Group the functions appropriately in the header.
I ended up getting rid of most of the explanatory comments since many of them
duplicated what was in the value_string.c file (and were out of sync with the
recent updates I made to those in r48633). Presumably most of the comments
should be in the .h file not the .c file, but there's enough churn ahead that
it's not worth fixing yet.

epan/show_exception.c, as it's used outside
epan/dissectors/packet-frame.c. Update their callers to include
<epan/show_exception.h> to get their declaration.
Add a CATCH_NONFATAL_ERRORS macro that catches all exceptions that, if
there's more stuff in the packet to dissect after the dissector call
that threw the exception, doesn't mean you shouldn't go ahead and
dissect that stuff. Use it in all those cases, including ones where
BoundsError was inappropriately being caught (you want those passed up
to the top level, so that the packet is reported as having been cut
short in the capture process).
Add a CATCH_BOUNDS_ERRORS macro that catches all exceptions that
correspond to running past the end of the data for a tvbuff; use it
rather than explicitly catching those exceptions individually, and
rather than just catching all exceptions (the only place that
DissectorError should be caught, for example, is at the top level, so
dissector bugs show up in the protocol tree).
Don't catch and then immediately rethrow exceptions without doing
anything else; just let the exceptions go up to the final catcher.
Use show_exception() to report non-fatal errors, rather than doing it
yourself.
If a dissector is called from Lua, catch all non-fatal errors and use
show_exception() to report them rather than catching only
ReportedBoundsError and adding a proto_malformed item.
Don't catch exceptions when constructing a trailer tvbuff in
packet-ieee8023.c - just construct it after the payload has been
dissected, and let whatever exceptions that throws be handled at the top
level.
Avoid some TRY/CATCH/ENDTRY cases by using checks such as
tvb_bytes_exist() before even looking in the tvbuff.

Dissector for HSR and PRP-1
Here is a patch that adds a dissector for HSR and for PRP-1. Both protocols are defined in IEC62439 Part 3. (High-availability Seamless Redundancy / Parallel Redundancy Protocol)
The existing PRP dissector has been refactored to support both the old PRP (now called PRP-0) and the new PRP-1.
There are three distinct dissectors:
- HSR (ethertype 892F)
- HSR/PRP supervision (ethertype 88FB)
- PRP-0 and PRP-1 (trailer dissector; disabled by default)
From me :
* Fix Clang Warning
* Add modification for CMakeLists.txt

keys to have _uint in their names, to match the routines that handle
dissector tables with string keys. (Using _port can confuse people into
thinking they're intended solely for use with TCP/UDP/etc. ports when,
in fact, they work better for things such as Ethernet types, where the
binding of particular values to particular protocols are a lot
stronger.)

Add support for dissecting TDLS (IEEE 802.11z) frames.
These are mostly used as Action frames that are encapsulated in Data frames (to go through any AP).

draft-ietf-isis-ext-eth specifies an extension to current Ethernet Frame
specifications for hardware and frame format to support payloads greater than
1500 Bytes for Type interpretation and Length interpretation frames.
The extension introduced by draft-ietf-isis-ext-eth is currently used by Cisco
Systems' IS-IS routing protocol implementation when running IS-IS over Ethernet
links with large MTU.

This is necessary in case a subdissector had changed it but was unable to
restore it (due to the exception).
Remove check_col().
svn path=/trunk/; revision=34436
From me: A few minor changes:
- col-clear() not req'd;
- Use 'gint32 length' rather than 'guint8 length';
- Use ENC_NA instead of FALSE/TRUE in two cases;
- Move global tdmoe_handle to be local to proto_reg_handoff...

This is a dissector for the Parallel Redundancy Protocol (PRP) defined in chapter
6 of the IEC 62439.
PRP uses two independent networks in parallel and allows redundancy without
switchovers.
The protocol is sending Mac multicast messages with Ethertype 0x88fb. In
addition to that it adds to every Ethernet frame a 4 byte trailer before
the FCS. The trailer is detected by checking a size field and an identifier
which are part of the trailer. Therefore, if the last 4 bytes of a frame
match a correct trailer they get interpreted as a trailer, although it was
probably not a real one.
Note:
This is a post-dissector which means it gets called for every frame. So as
to not cause a performance hit for every Wireshark user (who may not even be
looking at Ethernet frames) it currently disables itself every time Wireshark
starts up. (There should be a better way to do this--maybe different Profiles
(as discussed on -dev recently) is the way to go.)
From me:
Put ETHERTYPE_PRP (not IANA registered) in etypes.h and packet-ethertype.c

This patch adds a heuristic dissector to the ethernet trailer under the
keystring "eth.trailer". This allows for other protocol plugins which coopt
the ethernet trailer for their own devices to register for trailer traffic
without requiring any further changes to the executable.
