    The problem may be summarized as follows:
    1. A SA is established and its filter is
       installed with the last port fields set
       to x'FFFF'.
    2. An attempt is made to establish a second
       SA, but the filter is built with the last
       port fields different (x'0000' as opposed
       to x'FFFF') from the first filter.
    3. The installation of the second filter fails
       because of the difference between the two
       filters.  EZD0953I is seen.
    4. The second SA establishment fails.
