Add a new Wiretap encapsulation type WTAP_ENCAP_FDDI_BITSWAPPED, meaning
"FDDI with the MAC addresses bit-swapped"; whether the MAC addresses are
bit-swapped is a property of the machine on which the capture was taken,
not of the machine on which the capture is being read - right now, none
of the capture file formats we read indicate whether FDDI MAC addresses
are bit-swapped, but this does let us treat non-"libpcap" captures as
being bit-swapped or not bit-swapped independent of the machine on which
they're being read (and of the machine on which they were captured, but
I have the impression they're bit-swapped on most platforms), and allows
us to, if, as, and when we implement packet capture in Wiretap, mark
packets in a capture file written in Wiretap-native format based on the
machine on which they are captured (assuming the rule "Ultrix, Alpha,
and BSD/OS are the only platforms that don't bit-swap", or some other
compile-time rule, gets the right answer, or that some platform has
drivers that can tell us whether the addresses are bit-swapped).
(NOTE: if, for any of the capture file formats used only on one
platform, FDDI MAC addresses aren't bit-swapped, the code to read that
capture file format should be fixed to flag them as not bit-swapped.)
Use the encapsulation type to decide whether to bit-swap addresses in
"dissect_fddi()".

Have the IPX code set "pi.len" and "pi.captured_len" based on the length
in the IPX header, and have the dissectors it calls use it rather than
being passed the length as an argument.
Treat both packet type 20 ("WAN Broadcast") and 4 ("IPX", although 3 is
also "IPX", according to Network Monitor) as potentially being NetBIOS
packets.
The packet types for the IPX NetBIOS socket (0x0455) and the NWLink
sockets (0x0551 and 0x0553) are different (perhaps because there's one
socket for the 0x0455 NBIPX, so you have to do name service and datagram
service and have the packet types distinguish them, but NWLink has
separate sockets for name service and datagram service).
The packet type for name service and for datagram service are at
*different locations* in the packet, which is unfortunate if you want to
use the packet type to distinguish name service and datagram service
packets. Use the packet length, for now, to distinguish them, with
socket 0x0455.
Dissect datagram packets differently from name service packets.
Export "packet-netbios.c"'s "netbios_add_name()" routine, and use it
when dissecting NBIPX packets as well.
Label NBIPX packets as "NBIPX" rather than "NetBIOS".

Check in Olivier Abad's patch to add dissectors for LAP-B and X.25, and
wiretap support for RADCOM Ltd.'s WAN/LAN analyzers (see
http://www.radcom-inc.com/
). Note: as I remember, IEEE 802.2/ISO 8022 LLC has somewhat of an SDLC
flavor to it, just as I think LAP, LAPB, LAPD, and so on do, so we may
be able to combine some of the LLC dissection and the LAPB dissection
into common code that could, conceivably be used for other SDLC-flavored
protocols.
Make "S" a mnemonic for "Summary" in the "Tools" menu.
Move the routine, used for the "Tools/Summary" display, that turns a
wiretap file type into a descriptive string for it into the wiretap
library itself, expand on some of its descriptions, and add an entry for
files from a RADCOM analyzer.
Have "Tools/Summary" display the snapshot length for the capture.
