* GED125
* This is Cisco's protocol that runs atop TCP (ged125 is in the payload of TCP).
* The protocol serves as a way for the ICM and the VRU to communicate to each
* other in Cisco's CVP. The spec sheet that was used to write this dissector was
* Revision 3.1a of November 26, 2007.
*
* Protocol Structure
*
* All messages have an eight byte header. The first 4 bytes represent the package
* length. This length doesn't include the length of the base header. Next, is the
* message base type which is also 4 bytes. All ged125 messages have this format
* unless a message spans across several packets. The most common message is the
* service control type. This message type will have its own header and with in
* that header have a few other things. One of these things is a sub-message type.
