/*
 * T_PRIM_HEADER
 *
 * Description :  This type definition defines the custom specific
 *                part of a primitive. All primitives have the
 *                general format: header followed by data. The
 *                header of a primitive is changeable according to
 *                the requirements of the target system.
 * Hints:         Only the operation code opc as a USHORT value must
 *                be present. For multi-instance protocol stacks
 *                the routing information must be include in the
 *                header (T_ROUTE route).
