OK.  I guess I don't fully comprehend the process of normalization.  I
thought I understood it to me the reassembly of fragmented packets as

expected input (removal of unicode, etc.)  Is my understanding
incorrect?  Does it require both sides of the conversation to
normalize the input to those ports?

rpc_decode normalizes the RPC over TCP message segmentation format.
It's really naive and just assumes that traffic on said port is rpc
traffic.

It doesn't require both sides of the conversation and it can't use it,
even if it has it.
