301 * On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that

303 * mapping, so it probably supports capturing on the pfsync device

306 * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC;
307 * their libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would
308 * use 18 in pcap files as well.
309 *
310 * NetBSD and DragonFly BSD also use 18 for DLT_PFSYNC; their
311 * libpcaps do DLT_ <-> LINKTYPE_ mapping, and neither has an entry
312 * for DLT_PFSYNC, so it might not be able to write out dump files
313 * with 18 as the link-layer header type. (Earlier versions might
314 * not have done mapping, in which case they'd work the same way
315 * OpenBSD does.)
316 *
317 * Mac OS X defines it as 18, but doesn't appear to use it as of

327 * use 18. Code that uses pcap_datalink() to determine the link-layer
328 * header type of a savefile won't, when built and run on FreeBSD,

1188 * Sadly, the folks at Apple either had no clue that the DLT_USERn values
1189 * are for internal use within an organization and partners only, and
1190 * didn't know that the right way to get a link-layer header type is to
1191 * ask tcpdump.org for one, or knew and didn't care, so they just
1192 * used DLT_USER2, which causes problems for everything except for
1193 * their version of tcpdump.
1194 *
1195 * So I'll just give them one; hopefully this will show up in a
1196 * libpcap release in time for them to get this into 10.10 Big Sur
1197 * or whatever Mavericks' successor is called. LINKTYPE_PKTAP
1198 * will be 258 *even on OS X*; that is *intentional*, so that
1199 * PKTAP files look the same on *all* OSes (different OSes can have
1200 * different numerical values for a given DLT_, but *MUST NOT* have
1201 * different values for what goes in a file, as files can be moved
1202 * between OSes!).
1203 *
1204 * When capturing, on a system with a Darwin-based OS, on a device
1205 * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
1206 * version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP,
1207 * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
1208 * binary compatibility with Mavericks is preserved for programs using
1209 * this version of libpcap. This does mean that if you were using
1210 * DLT_USER2 for some capture device on OS X, you can't do so with
1211 * this version of libpcap, just as you can't with Apple's libpcap -
1212 * on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't
1213 * be able to distinguish between PKTAP and whatever you were using
1214 * DLT_USER2 for.
1215 *
1216 * If the program saves the capture to a file using this version of
1217 * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
1218 * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
1219 * That way, the file will *not* be a DLT_USER2 file. That means
1220 * that the latest version of tcpdump, when built with this version
1221 * of libpcap, and sufficiently recent versions of Wireshark will
1222 * be able to read those files and interpret them correctly; however,
1223 * Apple's version of tcpdump in OS X 10.9 won't be able to handle
1224 * them. (Hopefully, Apple will pick up this version of libpcap,
1225 * and the corresponding version of tcpdump, so that tcpdump will
1226 * be able to handle the old LINKTYPE_USER2 captures *and* the new
1227 * LINKTYPE_PKTAP captures.)
