The raw packet will go through the detection engine.  If there is any
reassembly, those pseudo packets will also go through.

If the alert is generated by the raw packet, the raw packet will be
logged.  In case of a reassembled pseudo packet, only the pseudo packet
will be logged - no way currently to log the actual packet.

These are related to the potential multiple levels of reassembly in the
preprocessor.
