/* 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_fd_open()" 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.
*
* 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

*
* 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 pcap-ng 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 pcap-ng 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 distingiush 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.
