37 /* Encapsulation types. Choose names that truly reflect
38 * what is contained in the packet trace file.
40 * WTAP_ENCAP_PER_PACKET is a value passed to "wtap_dump_open()" or
41 * "wtap_dump_fd_open()" to indicate that there is no single encapsulation
42 * type for all packets in the file; this may cause those routines to
43 * fail if the capture file format being written can't support that.
44 * It's also returned by "wtap_file_encap()" for capture files that
45 * don't have a single encapsulation type for all packets in the file.
47 * WTAP_ENCAP_UNKNOWN is returned by "wtap_pcap_encap_to_wtap_encap()"
48 * if it's handed an unknown encapsulation.
50 * WTAP_ENCAP_FDDI_BITSWAPPED is for FDDI captures on systems where the
51 * MAC addresses you get from the hardware are bit-swapped. Ideally,
52 * the driver would tell us that, but I know of none that do, so, for
53 * now, we base it on the machine on which we're *reading* the
54 * capture, rather than on the machine on which the capture was taken
55 * (they're probably likely to be the same). We assume that they're
56 * bit-swapped on everything except for systems running Ultrix, Alpha
57 * systems, and BSD/OS systems (that's what "tcpdump" does; I guess
58 * Digital decided to bit-swap addresses in the hardware or in the
59 * driver, and I guess BSDI bit-swapped them in the driver, given that
60 * BSD/OS generally runs on Boring Old PC's). If we create a wiretap
61 * save file format, we'd use the WTAP_ENCAP values to flag the
62 * encapsulation of a packet, so there we'd at least be able to base
63 * it on the machine on which the capture was taken.
65 * WTAP_ENCAP_LINUX_ATM_CLIP is the encapsulation you get with the
66 * ATM on Linux code from <http://linux-atm.sourceforge.net/>;
67 * that code adds a DLT_ATM_CLIP DLT_ code of 19, and that
68 * encapsulation isn't the same as the DLT_ATM_RFC1483 encapsulation
69 * presumably used on some BSD systems, which we turn into
70 * WTAP_ENCAP_ATM_RFC1483.
72 * WTAP_ENCAP_NULL corresponds to DLT_NULL from "libpcap". This
75 * 1) PPP-over-HDLC encapsulation, at least with some versions
76 * of ISDN4BSD (but not the current ones, it appears, unless
77 * I've missed something);
79 * 2) a 4-byte header containing the AF_ address family, in
80 * the byte order of the machine that saved the capture,
81 * for the packet, as used on many BSD systems for the
82 * loopback device and some other devices, or a 4-byte header
83 * containing the AF_ address family in network byte order,
84 * as used on recent OpenBSD systems for the loopback device;
86 * 3) a 4-byte header containing 2 octets of 0 and an Ethernet
87 * type in the byte order from an Ethernet header, that being
88 * what older versions of "libpcap" on Linux turn the Ethernet
89 * header for loopback interfaces into (0.6.0 and later versions
90 * leave the Ethernet header alone and make it DLT_EN10MB). */
