300 * 121 was reserved for Siemens HiPath HDLC on 2002-01-25, as

302 *
303 * On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that
304 * assigned 121 as DLT_PFSYNC. In current versions, its libpcap
305 * does DLT_ <-> LINKTYPE_ mapping, mapping DLT_PFSYNC to a
306 * LINKTYPE_PFSYNC value of 246, so it should write out DLT_PFSYNC
307 * dump files with 246 as the link-layer header type. (Earlier
308 * versions might not have done mapping, in which case they would
309 * have written them out with a link-layer header type of 121.)
310 *
311 * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC;
312 * its libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would
313 * write out DLT_PFSYNC dump files with use 18 as the link-layer
314 * header type.
315 *
316 * NetBSD, DragonFly BSD, and Darwin also use 18 for DLT_PFSYNC; in
317 * current versions, their libpcaps do DLT_ <-> LINKTYPE_ mapping,
318 * mapping DLT_PFSYNC to a LINKTYPE_PFSYNC value of 246, so they
319 * should write out DLT_PFSYNC dump files with 246 as the link-layer
320 * header type. (Earlier versions might not have done mapping,
321 * in which case they'd work the same way OpenBSD does, writing
322 * them out with a link-layer header type of 18.)
323 *
324 * We'll define DLT_PFSYNC as:
325 *
326 * 18 on NetBSD, OpenBSD, DragonFly BSD, and Darwin;
327 *
328 * 121 on FreeBSD;
329 *
330 * 246 everywhere else.
331 *
332 * We'll define DLT_HHDLC as 121 on everything except for FreeBSD;
333 * anybody who wants to compile, on FreeBSD, code that uses DLT_HHDLC
334 * is out of luck.
335 *
336 * We'll define LINKTYPE_PFSYNC as 246 on *all* platforms, so that
337 * savefiles written using *this* code won't use 18 or 121 for PFSYNC,
338 * they'll all use 246.
339 *
340 * Code that uses pcap_datalink() to determine the link-layer header
341 * type of a savefile won't, when built and run on FreeBSD, be able
342 * to distinguish between LINKTYPE_PFSYNC and LINKTYPE_HHDLC capture
343 * files, as pcap_datalink() will give 121 for both of them. Code
344 * that doesn't, such as the code in Wireshark, will be able to
345 * distinguish between them.
346 *
347 * FreeBSD's libpcap won't map a link-layer header type of 18 - i.e.,
348 * DLT_PFSYNC files from OpenBSD and possibly older versions of NetBSD,
349 * DragonFly BSD, and macOS - to DLT_PFSYNC, so code built with FreeBSD's
350 * libpcap won't treat those files as DLT_PFSYNC files.
351 *
352 * Other libpcaps won't map a link-layer header type of 121 to DLT_PFSYNC;
353 * this means they can read DLT_HHDLC files, if any exist, but won't
354 * treat pcap files written by any older versions of FreeBSD libpcap that

1261 * Sadly, the folks at Apple either had no clue that the DLT_USERn values
1262 * are for internal use within an organization and partners only, and
1263 * didn't know that the right way to get a link-layer header type is to
1264 * ask tcpdump.org for one, or knew and didn't care, so they just
1265 * used DLT_USER2, which causes problems for everything except for
1266 * their version of tcpdump.
1267 *
1268 * So I'll just give them one; hopefully this will show up in a
1269 * libpcap release in time for them to get this into 10.10 Big Sur
1270 * or whatever Mavericks' successor is called. LINKTYPE_PKTAP
1271 * will be 258 *even on macOS*; that is *intentional*, so that
1272 * PKTAP files look the same on *all* OSes (different OSes can have
1273 * different numerical values for a given DLT_, but *MUST NOT* have
1274 * different values for what goes in a file, as files can be moved
1275 * between OSes!).
1276 *
1277 * When capturing, on a system with a Darwin-based OS, on a device
1278 * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
1279 * version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP,
1280 * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
1281 * binary compatibility with Mavericks is preserved for programs using
1282 * this version of libpcap. This does mean that if you were using
1283 * DLT_USER2 for some capture device on macOS, you can't do so with
1284 * this version of libpcap, just as you can't with Apple's libpcap -
1285 * on macOS, they define DLT_PKTAP to be DLT_USER2, so programs won't
1286 * be able to distinguish between PKTAP and whatever you were using
1287 * DLT_USER2 for.
1288 *
1289 * If the program saves the capture to a file using this version of
1290 * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
1291 * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
1292 * That way, the file will *not* be a DLT_USER2 file. That means
1293 * that the latest version of tcpdump, when built with this version
1294 * of libpcap, and sufficiently recent versions of Wireshark will
1295 * be able to read those files and interpret them correctly; however,
1296 * Apple's version of tcpdump in OS X 10.9 won't be able to handle
1297 * them. (Hopefully, Apple will pick up this version of libpcap,
1298 * and the corresponding version of tcpdump, so that tcpdump will
1299 * be able to handle the old LINKTYPE_USER2 captures *and* the new
