314 * OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC;
315 * their libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would
316 * use 18 in pcap files as well.
317 *
318 * NetBSD and DragonFly BSD also use 18 for DLT_PFSYNC; their
319 * libpcaps do DLT_ <-> LINKTYPE_ mapping, and neither has an entry

321 * with 18 as the link-layer header type. (Earlier versions might
322 * not have done mapping, in which case they'd work the same way
323 * OpenBSD does.)

1196 *
1197 * Sadly, the folks at Apple either had no clue that the DLT_USERn values
1198 * are for internal use within an organization and partners only, and
1199 * didn't know that the right way to get a link-layer header type is to
1200 * ask tcpdump.org for one, or knew and didn't care, so they just
1201 * used DLT_USER2, which causes problems for everything except for
1202 * their version of tcpdump.
1203 *
1204 * So I'll just give them one; hopefully this will show up in a
1205 * libpcap release in time for them to get this into 10.10 Big Sur
1206 * or whatever Mavericks' successor is called. LINKTYPE_PKTAP
1207 * will be 258 *even on OS X*; that is *intentional*, so that
1208 * PKTAP files look the same on *all* OSes (different OSes can have
1209 * different numerical values for a given DLT_, but *MUST NOT* have
1210 * different values for what goes in a file, as files can be moved
1211 * between OSes!).
1212 *
1213 * When capturing, on a system with a Darwin-based OS, on a device
1214 * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
1215 * version of libpcap, the DLT_ value for the pcap_t will be DLT_PKTAP,
1216 * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
1217 * binary compatibility with Mavericks is preserved for programs using
1218 * this version of libpcap. This does mean that if you were using
1219 * DLT_USER2 for some capture device on OS X, you can't do so with
1220 * this version of libpcap, just as you can't with Apple's libpcap -
1221 * on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't
1222 * be able to distinguish between PKTAP and whatever you were using
1223 * DLT_USER2 for.
1224 *
1225 * If the program saves the capture to a file using this version of
1226 * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
1227 * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
1228 * That way, the file will *not* be a DLT_USER2 file. That means
1229 * that the latest version of tcpdump, when built with this version
1230 * of libpcap, and sufficiently recent versions of Wireshark will
1231 * be able to read those files and interpret them correctly; however,
1232 * Apple's version of tcpdump in OS X 10.9 won't be able to handle
1233 * them. (Hopefully, Apple will pick up this version of libpcap,
1234 * and the corresponding version of tcpdump, so that tcpdump will
1235 * be able to handle the old LINKTYPE_USER2 captures *and* the new
1236 * LINKTYPE_PKTAP captures.)
