for ip.ip_p and ip6.ip6_nxt (and other IPv6 header chain).
use val_to_str() as much as possible in dissect_{ipv6,pim,ripng}().
make --disable-zlib a default for netbsd (temporary workaround).

the base for numbers to be displayed in, bitmasks for bitfields, and blurbs
(which are one or two sentences describing the field).
proto_tree_add*() routines now automatically handle bitfields. You tell
it which header field you are adding, and just pass it the value of the
entire field, and the proto_tree routines will do the masking and shifting
for you.
This means that bitfields are more naturally filtered via dfilter now.
Added Phil Techau's support for signed integers in dfilters/proto_tree.
Added the beginning of the SNA dissector. It's not complete, but I'm
committing it now because it has example after example of how to use
bitfields with the new header_field_info struct and proto_tree routines.
It was the impetus to change how header_field_info works.

that the only options that contain *no* length byte are the IP and TCP
EOL and NOP options so that we can treat unknown options as
VARIABLE_LENGTH with a minimum of 2, and at least be able to move on to
the next option by using the length in the option, rather than just
reporting the unknown option and processing no options after it.

of option code, one octet of length (which includes the two option code
and length bytes), followed by 0 or more octets of option data, with
some options being fixed-length and some being variable-length. Put
some stuff from the PPP control protocol option parsing code into the
IP-and-TCP option parsing code, and use the latter instead of the
former.
(That code might also be usable for CDP as well, with some stuff added
to it.)
Shuffle the arguments to "dissect_ip_tcp_options()" to resemble those of
various other dissectors (i.e., with the "proto_tree *" at the end).
Add in code to dissect a pile of PPP options documented in various RFCs.

bunch of source files.
Replace the "payload" field of a "packet_info" structure with "len" and
"captured_len" fields, which contain the total packet length and total
captured packet length (including all headers) at the current protocol
layer (i.e., if a given layer has a length field, and that length field
says its shorter than the length we got from the capture, reduce the
"pi.len" and "pi.captured_len" values appropriately). Those fields can
be used in the future if we add checks to make sure a field we're
extracting from a packet doesn't go past the end of the packet, or past
the captured part of the packet.
Get rid of the additional payload argument to some dissection functions;
use "pi.captured_len - offset" instead.
Have the END_OF_FRAME macro use "pi.captured_len" rather than
"fd->cap_len", so that "dissect the rest of the frame" becomes "dissect
the rest of the packet", and doesn't dissect end-of-frame padding such
as padding added to make an Ethernet frame 60 or more octets long. (We
might want to rename it END_OF_PACKET; if we ever want to label the
end-of-frame padding for the benefit of people curious what that extra
gunk is, we could have a separate END_OF_FRAME macro that uses
"fd->cap_len".)

suggestion, this new method using a static array should use less memory
and be faster. It also has a nice side-effect of making the source-code
more readble, IMHO.
Changed the print routines to look for protocol proto_data instead of
looking at the text label as they did before, hoping that the data hex
dump field item starts with "Data (".
Added the -G keyword to ethereal to make it dump a glossary of display
filter keywords to stdout and exit. This data is then formatted with
the doc/dfilter2pod perl program to pod format, which is combined
with doc/ethereal.pod.template to create doc/ethereal.pod, from which
the ethereal manpage is created. This way we can keep the manpage up-to-date
with a list of fields that can be filtered on.

proto*() functions. The configure script tries to use ipv6 name resolution if
it knows the type of ipv6 stack the user has (this can be avoided with the
--disable-ipv6 switch) Additionally, the configure script now deals with wiretap
better. If the user doesn't want to compile wiretap, the wiretap is never
visited. A few unnecessary #includes were removed from some wiretap files, and
a CPP macro was moved from bpf.c to wtap.h.

reference the protocol tree with struct proto_tree and struct proto_item
objects. That way, the packet decoding source code file can be used with
non-gtk packet decoders, like a curses-based ethereal, e.g. I also re-arranged
some of the information in packet.h to more appropriate places (like other
packet-*.[ch] files).

because it is still in its infancy, but it can be compiled in optionally.
The library exists in its own subdirectory ethereal/wiretap. This patch also
edits all the packet-*.c files to remove the #include <pcap.h> line which is
unnecessary in these files. In the ethereal code, file.c is the most heavily
modified with #ifdef WITH_WIRETAP lines for the optional library.

it returns NULL, formats the value with the format passed in as
an argument, and returns a pointer to that static buffer.
Change several "match_strval()" calls to use "val_to_str()".
In "dissect_ospf()", use "match_strval()" to look up the packet
type, and use "Unknown" if it doesn't find a match.

1883, it should, perhaps with some additions, be able to handle IPv6
options as well).
Make the IPv4 and TCP dissectors use it.
Fix a typo in the IP dissector ("Unknon" for "Unknown").
Show the IP and TCP header lengths as byte counts rather than
4-byte-word counts.
Show the protocol field value of an IP header as a name if it's a
protocol we know about.
List the acknowledgment and urgent pointer values in a TCP header only
if the corresponding flag is set.
Make the ETT_ values members of an enum, so that the compiler
automatically assigns them sequential integer values (at least if said
compiler conforms to the ANSI C standard).
