Doing this brings up the issue with the byte-ordering of the payload
value set by the user. One on hand, the value is used to communicate
with the RMPP code, so could be in host-order. But on the other hand,
the value is in a data structure where all of the other fields are in
network-byte order...
I'm leaning towards network-byte order, which would set the payload to
the correct value for a single-segment RMPP MAD.
