* This was written to test what size TCP fragments would get through
* various TCP/IP packet filters, as used in IP firewalls. In certain
* conditions, enough of the TCP header is missing for unpredictable
* results unless the filter is aware that this can happen.
*
* See the IPFILTER.LICENCE file for details on licencing.
