I have built and tested a new Wireshark dissector which decodes a mirrored
packet that has an additional prepended UDP header attached to it.  The packet
format was designed by Juniper Networks.  I have tested this decoder on several
different packet captures (which I can provide if you wish) and it appears to
work the way I want it to.

A description of the packet format can be found here:
http://www.juniper.net/techpubs/en_US/junose10.2/information-products/topic-collections/policy-management/packet-mirror-prepended-header.html

It's currently in the form of a plugin since I followed some instructions
posted on how to build it as a plugin.  I mimicked the coding style as closely
as possible.

I tried to check it in using SVN but not surprisingly I got a denial.  So I'm
opening this ticked to see what can be done about that.  I have everything in
my setup under the C:\wireshark\plugins\jmirror directory.

I would like to submit the following files for review:
packet-jmirror.c
packet-jmirror.h
Makefile.nmake
moduleinfo.nmake
plugin.rc.in
Makefile.am
Makefile.common
README

Please contact me at [email protected] if you are interested in getting this
new packet decoder into the next release of Wireshark.

Thank you,
