/*
* ipsend.h (C) 1997-1998 Darren Reed
*
* 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.
*
* The author provides this program as-is, with no gaurantee for its
* suitability for any specific purpose. The author takes no responsibility
* for the misuse/abuse of this program and provides it for the sole purpose
* of testing packet filter policies. This file maybe distributed freely
* providing it is not modified and that this notice remains in tact.
