    Problem Text
    The test may fail on implementations because ic_len is less than or
    equal to max_size.

    I_STR Constructs an internal STREAMS ioctl() message from the data
    pointed to by arg, and sends that message downstream.
    To send requests downstream, arg must point to a strioctl
    structure.

    ic_len is the number of bytes in the data argument, and ic_dp is
    a pointer to the data argument. The ic_len member has two uses:
    on input, it contains the length of the data argument passed in,
    and on return from the command, it contains the number of bytes
    being returned to the process (the buffer pointed to by ic_dp
    should be large enough to contain the maximum amount of data
    that any module or the driver in the STREAM can return).

    The STREAM head will convert the information pointed to by the
    strioctl structure to an internal ioctl() command message and
    send it downstream.

    The ioctl() function with the I_STR command will fail if:

    [EINVAL] The ic_len member is less than 0 or larger than the
    maximum configured size of the data part of a message,
    or ic_timout is less than -1.

    "ic_len" needs to be set more than "max_size" (e.g. "max_size + 1")
    instead of "max_size".

    Test Output

    TEST PURPOSE #116
    EINVAL in errno and return -1 on a call to int
    ioctl(int fildes, I_STR, struct strioctl *arg) when
    fildes refers to a STREAMS device and the ic_len
    member of the structure pointed to by arg is larger
    than the maximum configured size of the data part of a
    message.
