Git commit
commit 7ef91b394d9e2e1a96f187069ced4e02707cb9b2
Author: Guy Harris <guy@xxxxxxxxxxxx>

    Handle the pseudo-trailer for the ATN extended checksums by passing in
    the source and destination address lengths and data, and adding them in,
    rather than by copying those fields to a fixed-size static buffer - that
    gets rid of a global variable (global variables considered harmful), and
    also means that we don't try to copy 24 bytes of length+address from
    packets that don't *have* 24 bytes of length+address (which caused
    exceptions to be thrown on some OSI captures I have).

    Construct some LI #defines out of other LI #defines, to make it a bit
    clearer why they have the values they do.

    Support the "additional information related to the clearing of the
    connection" variable part parameter of the COTP DR packet (which just
    means giving it a name, as its contents are user-defined - some HP-UX
    OSI stack appears to just stick in a string saying that it's said
    stack).

    Make the code that decodes the variable part of a DR packet look like
    the code that decodes the variable part of most other packets.

    For COTP CR packets, determine the class up front by checking whether
    the length is > 2.  (At some point we might want to associate a class
    indication with the COTP connection, if we see the connection setup,
    and, if we have that indication, use it in preference to the
    heuristics.)

    Make the code to handle various length indicator values in the ATN case
    more like the code in the non-ATN case.

    Dissect the variable part of COTP ER packets.

    Fix tpyos (TDPU->TPDU, tdpu->tpdu) and typpoes (accross->across).

    Clean up white space.
