Well at least I know what is happening here.  These messages come from
the decoder when it does not know how to handle the ethertype for the
packet (which in this case is 0x0).  Since it can't decode the packet,
it will just store the alert info into the database.  I would be
interested in seeing the data file that you are getting these from.
