dynamically-assigned "ett_" integer values, assigned by
"proto_register_subtree_array()"; this:
obviates the need to update "packet.h" whenever you add a new
subtree type - you only have to add a call to
"proto_register_subtree_array()" to a "register" routine and an
array of pointers to "ett_", if they're not already there, and
add a pointer to the new "ett_" variable to the array, if they
are there;
would allow run-time-loaded dissectors to allocate subtree types
when they're loaded.

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.

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.
svn path=/trunk/; revision=601
Add in the Identification and Time Remaining codes for LCP.
Add in a pile of other LCP options, albeit without anything more than
names for now.
Don't say "1 bytes", say "1 byte".
Don't use "dissect_data()" to dissect part of a *CP packet, and don't
dissect opaque data if there're zero bytes of it.
svn path=/trunk/; revision=578
Have a common routine to parse both LCP and IPCP, as IPCP is based on
LCP.
Have only one "value_string" array of PPP protocol types, with all the
types we know about.
svn path=/trunk/; revision=577
"dissect_payload_ppp()"; put it into a common routine, called by both
(which means we now dissect LCP and IPCP in PPP requests even if they
aren't inside PPPOE or GRE packets).

file formats. Libpcap is used only for capturing.

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.

Show the packet type as a string, as well as a hex number, in the detail
display. Show the packet type as a hex number in the summary display if
it's not a packet type we know about.
Don't put the "N on link, M captured" stuff in the PPP detail display,
as that's now in the frame detail display.
Handle IPv6, Appletalk, IPX, and Vines.

generalizes the column printing code, adds a "frame" tree item to
the tree view, and fixes a bunch of miscellaneous coding bugs.
