 372  * dli_version is 2 for the current version of the pseudo-header.

 381  * dli_pktlen is the length of the packet data following the pseudo-header

 636  * are for internal use within an organization and partners only, and
 637  * didn't know that the right way to get a link-layer header type is to
 638  * ask tcpdump.org for one, or knew and didn't care, so they just
 639  * used DLT_USER2, which causes problems for everything except for
 640  * their version of tcpdump.
 641  *
 642  * So I'll just give them one; hopefully this will show up in a
 643  * libpcap release in time for them to get this into 10.10 Big Sur
 644  * or whatever Mavericks' successor is called.  LINKTYPE_PKTAP
 645  * will be 258 *even on OS X*; that is *intentional*, so that
 646  * PKTAP files look the same on *all* OSes (different OSes can have
 647  * different numerical values for a given DLT_, but *MUST NOT* have
 648  * different values for what goes in a file, as files can be moved
 649  * between OSes!).
 650  *
 651  * When capturing, on a system with a Darwin-based OS, on a device
 652  * that returns 149 (DLT_USER2 and Apple's DLT_PKTAP) with this
 653  * version of libpcap, the DLT_ value for the pcap_t  will be DLT_PKTAP,
 654  * and that will continue to be DLT_USER2 on Darwin-based OSes. That way,
 655  * binary compatibility with Mavericks is preserved for programs using
 656  * this version of libpcap.  This does mean that if you were using
 657  * DLT_USER2 for some capture device on OS X, you can't do so with
 658  * this version of libpcap, just as you can't with Apple's libpcap -
 659  * on OS X, they define DLT_PKTAP to be DLT_USER2, so programs won't
 660  * be able to distinguish between PKTAP and whatever you were using
 661  * DLT_USER2 for.
 662  *
 663  * If the program saves the capture to a file using this version of
 664  * libpcap's pcap_dump code, the LINKTYPE_ value in the file will be
 665  * LINKTYPE_PKTAP, which will be 258, even on Darwin-based OSes.
 666  * That way, the file will *not* be a DLT_USER2 file.  That means
 667  * that the latest version of tcpdump, when built with this version
 668  * of libpcap, and sufficiently recent versions of Wireshark will
 669  * be able to read those files and interpret them correctly; however,
 670  * Apple's version of tcpdump in OS X 10.9 won't be able to handle
 671  * them.  (Hopefully, Apple will pick up this version of libpcap,
 672  * and the corresponding version of tcpdump, so that tcpdump will
 673  * be able to handle the old LINKTYPE_USER2 captures *and* the new
