The attached patch includes several enhancements to the Control Code field
dissection in the DNP3 dissector:
1. The Operation Type, Queue / Clear and Trip Cotnrol Code are now fields that
captures can be filtered on.
2. The Control Code is now broken out in the dissection to show the individual
fields and mapping into the byte fields
3. The count, on-time, off-time and status fields are shown on the appropriate
bytes
4. The source code comments and some of the source code names are modified to
better reflect the DNP3 specification naming conventions
