In certain 824583Sdarrenr * conditions, enough of the TCP header is missing for unpredictable 924583Sdarrenr * results unless the filter is aware that this can happen. 1024583Sdarrenr * 11145510Sdarrenr * The author provides this program as-is, with no gaurantee for its 12145510Sdarrenr * suitability for any specific purpose.
