    Problem Text
    The test case attempts to test the read-only option TCP_MAXSEG for the
    TCP transport provider. However, in creating the option buffer, the
    option level is set to ISO_TP (see userintf.c below), which the provider
    does not understand. The provider correctly discards the option with
    an unknown level during the t_connect() call, based on the XTI CAE
    Specification, section 5.3.2, "Illegal Options". The t_connect() call
    therefore returns 0 instead of a TACCES or TLOOK error.

    static struct t_optmgmt req;
    static struct t_opthdr reqopt[64];

    if (!speclevel)
    level = ANY_LEVEL;

    req.flags = T_NEGOTIATE;
    req.opt.buf = (char *) reqopt;
    req.opt.len = 0;
    req.opt.maxlen = sizeof(reqopt);

    if (provider == PD_TCP)
    {
    foundprovider++;

    switch (level)
    {
    case ANY_LEVEL:
    case INET_TCP:
    /* use TCP_MAXSEG in any state */
    if (getoptlist(INET_TCP, TCP_MAXSEG, 0, state, &
    value, &len, 0) != -1)
    addoption(&req.opt, &popt, ISO_TP,
    TCP_MAXSEG, (void *)value, len);

    Review Response
    The file "userintf.c" is a user configurable and cannot be guaranteed to be
    consistent across all systems. It is the user's responsibility to make the
    appropriate changes to this file and it is suggested that, while it is
    recognised that this is an error in the file, the user makes the change from
    ISO_TP to INET_TCP in the appropriate place in this file. The test suite
    should then be recompiled and re-executed.

    It is recommended that this request is refused.
