/* Encapsulation types. Choose names that truly reflect
 * what is contained in the packet trace file.
 *
 * WTAP_ENCAP_PER_PACKET is a value passed to "wtap_dump_open()" or
 * "wtap_dump_fdopen()" to indicate that there is no single encapsulation
 * type for all packets in the file; this may cause those routines to
 * fail if the capture file format being written can't support that.
 * It's also returned by "wtap_file_encap()" for capture files that
 * don't have a single encapsulation type for all packets in the file.
 *
 * WTAP_ENCAP_UNKNOWN is returned by "wtap_pcap_encap_to_wtap_encap()"
 * if it's handed an unknown encapsulation. It is also used by file
 * types for encapsulations which are unsupported by libwiretap.
 *
 * WTAP_ENCAP_NONE is an initial value used by file types like pcapng
 * that do not have a single file level encapsulation type. If and when
 * something that indicate encapsulation is read, the encapsulation will
 * change (possibly to WTAP_ENCAP_PER_PACKET) and appropriate IDBs will
 * be generated. If a file type uses this value, it MUST provide IDBs
 * (possibly fake) when the encapsulation changes; otherwise, it should
 * return WTAP_ENCAP_UNKNOWN so that attempts to write an output file
 * without reading the entire input file first fail gracefully.
 *
 * WTAP_ENCAP_FDDI_BITSWAPPED is for FDDI captures on systems where the
 * MAC addresses you get from the hardware are bit-swapped.  Ideally,
 * the driver would tell us that, but I know of none that do, so, for
 * now, we base it on the machine on which we're *reading* the
 * capture, rather than on the machine on which the capture was taken
 * (they're probably likely to be the same).  We assume that they're
 * bit-swapped on everything except for systems running Ultrix, Alpha
 * systems, and BSD/OS systems (that's what "tcpdump" does; I guess
 * Digital decided to bit-swap addresses in the hardware or in the
 * driver, and I guess BSDI bit-swapped them in the driver, given that
 * BSD/OS generally runs on Boring Old PC's).  If we create a wiretap
 * save file format, we'd use the WTAP_ENCAP values to flag the
 * encapsulation of a packet, so there we'd at least be able to base
 * it on the machine on which the capture was taken.
 *
 * WTAP_ENCAP_LINUX_ATM_CLIP is the encapsulation you get with the
 * ATM on Linux code from <http://linux-atm.sourceforge.net/>;
 * that code adds a DLT_ATM_CLIP DLT_ code of 19, and that
 * encapsulation isn't the same as the DLT_ATM_RFC1483 encapsulation
 * presumably used on some BSD systems, which we turn into
 * WTAP_ENCAP_ATM_RFC1483.
 *
 * WTAP_ENCAP_NULL corresponds to DLT_NULL from "libpcap".  This
 * corresponds to
 *
 *  1) PPP-over-HDLC encapsulation, at least with some versions
 *     of ISDN4BSD (but not the current ones, it appears, unless
 *     I've missed something);
 *
 *  2) a 4-byte header containing the AF_ address family, in
 *     the byte order of the machine that saved the capture,
 *     for the packet, as used on many BSD systems for the
 *     loopback device and some other devices, or a 4-byte header
 *     containing the AF_ address family in network byte order,
 *     as used on recent OpenBSD systems for the loopback device;
 *
 *  3) a 4-byte header containing 2 octets of 0 and an Ethernet
 *     type in the byte order from an Ethernet header, that being
 *     what older versions of "libpcap" on Linux turn the Ethernet
 *     header for loopback interfaces into (0.6.0 and later versions
 *     leave the Ethernet header alone and make it DLT_EN10MB). */

/*
 * Record type values.
 *
 * This list will expand over time, so don't assume everything will
 * forever be one of the types listed below.
 *
 * For file-type-specific records, the "ftsrec" field of the pseudo-header
 * contains a file-type-specific subtype value, such as a block type for
 * a pcapng file.
 *
 * An "event" is an indication that something happened during the capture
 * process, such as a status transition of some sort on the network.
 * These should, ideally, have a time stamp and, if they're relevant to
 * a particular interface on a multi-interface capture, should also have
 * an interface ID.  The data for the event is file-type-specific and
 * subtype-specific.  These should be dissected and displayed just as
 * packets are.
 *
 * A "report" supplies information not corresponding to an event;
 * for example, a pcapng Interface Statistics Block would be a report,
 * as it doesn't correspond to something happening on the network.
 * They may have a time stamp, and should be dissected and displayed
 * just as packets are.
 *
 * We distinguish between "events" and "reports" so that, for example,
 * the packet display can show the delta between a packet and an event
 * but not show the delta between a packet and a report, as the time
 * stamp of a report may not correspond to anything interesting on
 * the network but the time stamp of an event would.
 *
 * XXX - are there any file-type-specific records that *shouldn't* be
 * dissected and displayed?  If so, they should be parsed and the
 * information in them stored somewhere, and used somewhere, whether
 * it's just used when saving the file in its native format or also
 * used to parse *other* file-type-specific records.
 *
 * These would be similar to, for example, pcapng Interface Description
 * Blocks, for which the position within the file is significant only
 * in that an IDB for an interface must appear before any packets from
 * the interface; the fact that an IDB appears at some point doesn't
 * necessarily mean something happened in the capture at that point.
 * Name Resolution Blocks are another example of such a record.
 *
 * (XXX - if you want to have a record that says "this interface first
 * showed up at this time", that needs to be a separate record type
 * from the IDB.  We *could* add a "New Interface Description Block",
 * with a time stamp, for that purpose, but we'd *still* have to
 * provide IDBs for those interfaces, for compatibility with programs
 * that don't know about the NIDB.  An ISB with only an isb_starttime
 * option would suffice for this purpose, so nothing needs to be
 * added to pcapng for this.)
