/*

* We don't write DLT_* values to capture files, because they're not the

* same on all platforms.

*

* Unfortunately, the various flavors of BSD have not always used the same

* numerical values for the same data types, and various patches to

* libpcap for non-BSD OSes have added their own DLT_* codes for link

* layer encapsulation types seen on those OSes, and those codes have had,

* in some cases, values that were also used, on other platforms, for other

* link layer encapsulation types.

*

* This means that capture files of a type whose numerical DLT_* code

* means different things on different BSDs, or with different versions

* of libpcap, can't always be read on systems other than those like

* the one running on the machine on which the capture was made.

*

* Instead, we define here a set of LINKTYPE_* codes, and map DLT_* codes

* to LINKTYPE_* codes when writing a savefile header, and map LINKTYPE_*

* codes to DLT_* codes when reading a savefile header.

*

* For those DLT_* codes that have, as far as we know, the same values on

* all platforms (DLT_NULL through DLT_FDDI), we define LINKTYPE_xxx as

* DLT_xxx; that way, captures of those types can still be read by

* versions of libpcap that map LINKTYPE_* values to DLT_* values, and

* captures of those types written by versions of libpcap that map DLT_

* values to LINKTYPE_ values can still be read by older versions

* of libpcap.

*

* The other LINKTYPE_* codes are given values starting at 100, in the

* hopes that no DLT_* code will be given one of those values.

*

* In order to ensure that a given LINKTYPE_* code's value will refer to

* the same encapsulation type on all platforms, you should not allocate

* a new LINKTYPE_* value without consulting

* "tcpdump-workers@lists.tcpdump.org". The tcpdump developers will

* allocate a value for you, and will not subsequently allocate it to

* anybody else; that value will be added to the "pcap.h" in the

* tcpdump.org Git repository, so that a future libpcap release will

* include it.

*

* You should, if possible, also contribute patches to libpcap and tcpdump

* to handle the new encapsulation type, so that they can also be checked

* into the tcpdump.org Git repository and so that they will appear in

* future libpcap and tcpdump releases.

*

* Do *NOT* assume that any values after the largest value in this file

* are available; you might not have the most up-to-date version of this

* file, and new values after that one might have been assigned. Also,

* do *NOT* use any values below 100 - those might already have been

* taken by one (or more!) organizations.

*

* Any platform that defines additional DLT_* codes should:

*

* request a LINKTYPE_* code and value from tcpdump.org,

* as per the above;

*

* add, in their version of libpcap, an entry to map

* those DLT_* codes to the corresponding LINKTYPE_*

* code;

*

* redefine, in their "net/bpf.h", any DLT_* values

* that collide with the values used by their additional

* DLT_* codes, to remove those collisions (but without

* making them collide with any of the LINKTYPE_*

* values equal to 50 or above; they should also avoid

* defining DLT_* values that collide with those

* LINKTYPE_* values, either).

* the pseudo-header is:

*

* struct dl_ipnetinfo {

* u_int8_t dli_version;

* u_int8_t dli_family;

* u_int16_t dli_htype;

* u_int32_t dli_pktlen;

* u_int32_t dli_ifindex;

* u_int32_t dli_grifindex;

* u_int32_t dli_zsrc;

* u_int32_t dli_zdst;

* };

*

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

*

* dli_family is a Solaris address family value, so it's 2 for IPv4

* and 26 for IPv6.

*

* dli_htype is a "hook type" - 0 for incoming packets, 1 for outgoing

* packets, and 2 for packets arriving from another zone on the same

* machine.

*

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

* (so the captured length minus dli_pktlen is the length of the

* pseudo-header, assuming the entire pseudo-header was captured).

*

* dli_ifindex is the interface index of the interface on which the

* packet arrived.

*

* dli_grifindex is the group interface index number (for IPMP interfaces).

*

* dli_zsrc is the zone identifier for the source of the packet.

*

* dli_zdst is the zone identifier for the destination of the packet.

*

* A zone number of 0 is the global zone; a zone number of 0xffffffff

* means that the packet arrived from another host on the network, not

* from another zone on the same machine.

*

* An IPv4 or IPv6 datagram follows the pseudo-header; dli_family indicates

* which of those it is.
