- * 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 OS X*; 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 OS X, you can't do so with
- * this version of libpcap, just as you can't with Apple's libpcap -
- * on OS X, 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
