	3	* We use the "receiver-makes-right" approach to byte order,
	4	* because time is at a premium when we are writing the file.
	5	* In other words, the pcap_file_header and pcap_pkthdr,
	6	* records are written in host byte order.
	7	* Note that the bytes of packet data are written out in the order in
	8	* which they were received, so multi-byte fields in packets are not
	9	* written in host byte order, they're written in whatever order the
	10	* sending machine put them in.
	11	*
	12	* ntoh[ls] aren't sufficient because we might need to swap on a big-endian
	13	* machine (if the file was written in little-end order).
