Process it in libwiretap; no need to hand it to libwireshark for dissection, it can just dissect the radio information pseudo-header with the processed information.

/* Encapsulation types. Choose names that truly reflect
|
|
* what is contained in the packet trace file.
|
|
*
|
|
* WTAP_ENCAP_PER_PACKET is a value passed to "wtap_dump_open()" or
|
|
* "wtap_dump_fd_open()" to indicate that there is no single encapsulation
|
|
* type for all packets in the file; this may cause those routines to
|
|
* fail if the capture file format being written can't support that.
|
|
* It's also returned by "wtap_file_encap()" for capture files that
|
|
* don't have a single encapsulation type for all packets in the file.
|
|
*
|
|
* WTAP_ENCAP_UNKNOWN is returned by "wtap_pcap_encap_to_wtap_encap()"
|
|
* if it's handed an unknown encapsulation.
|
|
*
|
|
* WTAP_ENCAP_FDDI_BITSWAPPED is for FDDI captures on systems where the
|
|
* MAC addresses you get from the hardware are bit-swapped. Ideally,
|
|
* the driver would tell us that, but I know of none that do, so, for
|
|
* now, we base it on the machine on which we're *reading* the
|
|
* capture, rather than on the machine on which the capture was taken
|
|
* (they're probably likely to be the same). We assume that they're
|
|
* bit-swapped on everything except for systems running Ultrix, Alpha
|
|
* systems, and BSD/OS systems (that's what "tcpdump" does; I guess
|
|
* Digital decided to bit-swap addresses in the hardware or in the
|
|
* driver, and I guess BSDI bit-swapped them in the driver, given that
|
|
* BSD/OS generally runs on Boring Old PC's). If we create a wiretap
|
|
* save file format, we'd use the WTAP_ENCAP values to flag the
|
|
* encapsulation of a packet, so there we'd at least be able to base
|
|
* it on the machine on which the capture was taken.
|
|
*
|
|
* WTAP_ENCAP_LINUX_ATM_CLIP is the encapsulation you get with the
|
|
* ATM on Linux code from <http://linux-atm.sourceforge.net/>;
|
|
* that code adds a DLT_ATM_CLIP DLT_ code of 19, and that
|
|
* encapsulation isn't the same as the DLT_ATM_RFC1483 encapsulation
|
|
* presumably used on some BSD systems, which we turn into
|
|
* WTAP_ENCAP_ATM_RFC1483.
|
|
*
|
|
* WTAP_ENCAP_NULL corresponds to DLT_NULL from "libpcap". This
|
|
* corresponds to
|
|
*
|
|
* 1) PPP-over-HDLC encapsulation, at least with some versions
|
|
* of ISDN4BSD (but not the current ones, it appears, unless
|
|
* I've missed something);
|
|
*
|
|
* 2) a 4-byte header containing the AF_ address family, in
|
|
* the byte order of the machine that saved the capture,
|
|
* for the packet, as used on many BSD systems for the
|
|
* loopback device and some other devices, or a 4-byte header
|
|
* containing the AF_ address family in network byte order,
|
|
* as used on recent OpenBSD systems for the loopback device;
|
|
*
|
|
* 3) a 4-byte header containing 2 octets of 0 and an Ethernet
|
|
* type in the byte order from an Ethernet header, that being
|
|
* what older versions of "libpcap" on Linux turn the Ethernet
|
|
* header for loopback interfaces into (0.6.0 and later versions
|
|
* leave the Ethernet header alone and make it DLT_EN10MB). */
