Wireshark expects 802.1ah Instance tags to have ethernet type 0x88f0, but latest
802.1ah draft 4.1 defines the 802.1ah Instance tag ethernet type to 0x88e7.

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

Attached is a patch file and a new dissector for FCoE. This protocol
is described at http://fcoe.com and has been submitted to T11. It is an encapsulation protocol that can be used to transport FC frames over raw Ethernet when the link is loss-free due to pause. The Ethertype 0x8906 has been reserved through IEEE for this protocol.

packet-cisco-wireless.c is actually trying to dissect WLCCP:
I have attached a dissector I wrote from scratch for the
frames that I'm seeing. It has #defines for the field offsets and
lengths so it should be easier to merge. I also attached a sample
capture with one of the frames that I'm seeing. There are more fields
in the frame I haven't yet figured out, hopefully your dissector has
those that I'm missing.
Me: - Commented in wlccp over udp as well, it works most of the time.
- Leave the file packet-cisco-wireless.c in for the time being to
copy over knowledge until no usable info is left in the file.

New protocol: epl v1
Hi,
in addition to the recently submitted dissector for the EPL v2 protocol,
this is the dissector for the first version of the EPL protocol.

new protocol: veritas low latency transport
---
Attached is a patch file that adds a new dissector for the LLT protocol
(Veritas Low Level Transport, used for server clustering). They use
ethertype 0xCAFE even though it isn't assigned to them :(. There are
other fields and possibly other message types directly between servers
it does not yet dissect as no one outside of Veritas knows what they
are. This dissector understands the one people will run across most -
multiple servers broadcasting these heartbeats all over the place. I
figured out these fields through many Internet searches.
I will add the protocol to the Wiki after it is committed.
Thanks,
Steve

directory to the epan directory. Some of them should perhaps ultimately
be moved to epan/dissectors, if they pertain only to stuff exported by a
particular dissector.
Fix Gerald's e-mail address in files we're moving.
