The Jargon File (version 4.4.7, 29 Dec 2003):

kamikaze packet
 n.

    The ?official? jargon for what is more commonly called a Christmas tree
    packet. RFC-1025, TCP and IP Bake Off says:

        10 points for correctly being able to process a ?Kamikaze? packet (AKA
        nastygram, christmas tree packet, lamp test segment, et al.). That is,
        correctly handle a segment with the maximum combination of features at
        once (e.g., a SYN URG PUSH FIN segment with options and data).

    See also Chernobyl packet.


The Free On-line Dictionary of Computing (30 December 2018):

Christmas tree packet
kamikaze packet

    (Or kamikaze packet) A packet with every single
   option set for whatever protocol is in use.  The term
   doubtless derives from a fanciful image of each little option
   bit being represented by a different-coloured light bulb, all
   turned on.

   RFC 1025, "TCP and IP Bake Off" says:

   10 points for correctly being able to process a "Kamikaze"
   packet (AKA nastygram, Christmas tree packet, lamp test
   segment, et al.).  That is, correctly handle a segment with
   the maximum combination of features at once (e.g. a SYN URG
   PUSH FIN segment with options and data).

   Compare: Chernobyl packet.
