The MAD layer can assume that any RMPP request that expects a response is DS
RMPP.  This is a simple check that doesn't involve looking at the class or
method.

If the check is incorrect, and it's an RMPP request followed by a non-RMPP
response, then we send an extra ACK of the final ACK.  I'm not sure if the extra
ACK would cause any problems.

No use cases.
