Description

There was work previously done to create two plugins for Wireshark to decode LNet and Lustre headers. That work is started in lustre/contrib as the files packet-lnet.c and packet-lustre.c.

Attempting to build these plugins revealed that Wireshark's API for dissectors has changed such they no longer build/run. Also, the Lustre plugin had a few syntax errors so I am not sure if it ever worked.

This feature request is to do the following upgrades to Wireshark support:

1- Get both plugins building under the latest 1.4.x version of Wireshark (will be backwards compatible with 1.2.x).
2- Move them to a wireshark subdirectory of lustre/contrib to isolate them better
3- Create a Makefile to build and install the plugins (one does not exist today).
4- If possible, automate the building of the plugins if the build system has the Wireshark source package installed.

A Wiki page should also be created to provide instruction on how to use Wireshark to look at LNet and Lustre packets.
