2 * ipsend.h (C) 1997-1998 Darren Reed
4 * This was written to test what size TCP fragments would get through
5 * various TCP/IP packet filters, as used in IP firewalls. In certain
6 * conditions, enough of the TCP header is missing for unpredictable
7 * results unless the filter is aware that this can happen.
9 * See the IPFILTER.LICENCE file for details on licencing.
