 * 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.
