** Class 1 connection values.

** Note that these values and the CM_CalcCPUtimeForConnection() function
** may not be used by every application.
** For example, the bridge object, BR, uses them to calculate the
** CPU time used by its connections.  However, other applications, such as
** a scanner, may use values defined for each of its application data areas
** instead.  In that case, the BF would calculate the CPU overhead time for
** the connection.
**
** These values are to be determined emperically.
** Example values are:
**       #define CPU_PKT_OVERHEAD         60L       /* 0.006% *//*
**       #define CPU_BYTE_OVERHEAD        19L       /* 0.0019%*//*

** Class 3 connections are not time critical and can therefore be handled by
** the CPU resource reserve that is guaranteed by GS_MIN_CPU_RESOURCE.
** However, once the CPU resource reaches the GS_MIN_CPU_RESOURCE value
** we want to start rejecting any new ones.  Therefore a small CPU resource
** value is reserved for Class 3 connections.
**
** An example value is CPU_1_PERCENT.
** The default value is 0.  Therefore, no CPU resource will be
** reserved for bridged CLASS3 connections unless this value is changed.
