* 121 was reserved for Siemens HiPath HDLC on 2002-01-25, as
* requested by Tomas Kukosa.
*
* On 2004-02-25, a FreeBSD checkin to sys/net/bpf.h was made that
* assigned 121 as DLT_PFSYNC. In current versions, its libpcap
* does DLT_ <-> LINKTYPE_ mapping, mapping DLT_PFSYNC to a
* LINKTYPE_PFSYNC value of 246, so it should write out DLT_PFSYNC
* dump files with 246 as the link-layer header type. (Earlier
* versions might not have done mapping, in which case they would
* have written them out with a link-layer header type of 121.)
*
* OpenBSD, from which pf came, however, uses 18 for DLT_PFSYNC;
* its libpcap does no DLT_ <-> LINKTYPE_ mapping, so it would
* write out DLT_PFSYNC dump files with use 18 as the link-layer
* header type.
*
* NetBSD, DragonFly BSD, and Darwin also use 18 for DLT_PFSYNC; in
* current versions, their libpcaps do DLT_ <-> LINKTYPE_ mapping,
* mapping DLT_PFSYNC to a LINKTYPE_PFSYNC value of 246, so they
* should write out DLT_PFSYNC dump files with 246 as the link-layer
* header type. (Earlier versions might not have done mapping,
* in which case they'd work the same way OpenBSD does, writing
* them out with a link-layer header type of 18.)
*
* We'll define DLT_PFSYNC as:
*
* 18 on NetBSD, OpenBSD, DragonFly BSD, and Darwin;
*
* 121 on FreeBSD;
*
* 246 everywhere else.
*
* We'll define DLT_HHDLC as 121 on everything except for FreeBSD;
* anybody who wants to compile, on FreeBSD, code that uses DLT_HHDLC
* is out of luck.
*
* We'll define LINKTYPE_PFSYNC as 246 on *all* platforms, so that
* savefiles written using *this* code won't use 18 or 121 for PFSYNC,
* they'll all use 246.
*
* Code that uses pcap_datalink() to determine the link-layer header
* type of a savefile won't, when built and run on FreeBSD, be able
* to distinguish between LINKTYPE_PFSYNC and LINKTYPE_HHDLC capture
* files, as pcap_datalink() will give 121 for both of them. Code
* that doesn't, such as the code in Wireshark, will be able to
* distinguish between them.
*
* FreeBSD's libpcap won't map a link-layer header type of 18 - i.e.,
* DLT_PFSYNC files from OpenBSD and possibly older versions of NetBSD,
* DragonFly BSD, and macOS - to DLT_PFSYNC, so code built with FreeBSD's
* libpcap won't treat those files as DLT_PFSYNC files.
*
* Other libpcaps won't map a link-layer header type of 121 to DLT_PFSYNC;
* this means they can read DLT_HHDLC files, if any exist, but won't
* treat pcap files written by any older versions of FreeBSD libpcap that
* didn't map to 246 as DLT_PFSYNC files.

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