protocols (where there's a virtual circuit ID of some sort in packets) what conversations are for protocols ultimately running atop connectionless network layers. Have circuit type and ID values in the "packet_info" structure. Have the Frame Relay dissector set the circuit type and ID values, and have the Wellfleet compression protocol set up circuit information and store compression information with the circuit. svn path=/trunk/; revision=6469

* XXX - this takes the plugin directory as an argument, because
|
|
* libethereal now has its own configure script and "config.h" file,
|
|
* which is what code in the "epan" directory includes, but we need
|
|
* to define PLUGIN_DIR in the top-level directory, as it's used by,
|
|
* for example, the Makefile for the Gryphon plugin, so it knows
|
|
* where to install the plugin.
|
|
*
|
|
* Eventually, we should probably have an "epan-configure" script
|
|
* (or "libethereal-configure", or whatever), along the lines of what
|
|
* GTK+ and GLib have, that can print, among other things, the directory
|
|
* into which plugins should be installed. That way, only libethereal
|
|
* need know what directory that is; programs using it won't, *and*
|
|
* Makefiles for plugins can just use "epan-configure" to figure out
|
|
* where to install the plugins.
|
|
*
|
|
* (Would that *more* libraries had configure scripts like that, so
|
|
* that configure scripts didn't have to go through various contortions
|
|
* to figure out where the header files and libraries for various
|
|
* libraries are located.)
