:Which macro/function can I used to replace "dtom"?

    It doesn't exist any more.  dtom() used to convert a data pointer
    to an mbuf pointer.  This was possible only as an artifact of the 
    original mbuf allocator implementation.  The macro was massively misused
    all over.

    When I rewrote that mbuf API last year I got rid of it.  There is 
    in fact, *NO* easy way to convert a data pointer to its related mbuf
    (nor would you want to).  Instead, all related code simply tracks the
    actual mbuf pointer (which is what it should have done in the first
    place).
