Make the "BYTES_ARE_IN_FRAME()" macro take a "captured length of the
packet" argument.
Add some length checks to capture routines.

for IGRP in the table in "ipproto.c".
Get rid of a duplicate entry for TCP in the same table, and also get rid
of the entry for IP_PROTO_IPV4 right after IP_PROTO_IPIP, as
IP_PROTO_IPIP and IP_PROTO_IPV4 are both 4.

statements.
Move the setting of the Protocol column in various dissectors before
anything is fetched from the packet, and also clear the Info column at
that point in those and some other dissectors, so that if an exception
is thrown, the columns don't reflect the previous protocol.
Make the IP dissector static, as it's called only via dissector tables
or dissector handles. Also make the "dissect the TOS field as the
DiffServ DS field" flag static, as it's not referred to outside of
"packet-ip.c".
In the NCP dissector, refer to the port type through "pinfo" rather than
through the global "pi", as it's a tvbuffified dissector.

doesn't just seem to be a profiling artifact) that, at least on FreeBSD
3.4, it's significantly more efficient to clear out a column by stuffing
a '\0' into the first byte of the column data than to do so by copying a
null string (I guess when copying one byte, the fixed overhead of the
procedure call and of "strcpy()" is significant).
Have the TCP dissector set the Protocol column, and clear the Info
column, before doing anything that might cause an exception to be
thrown, so that if we *do* get an exception thrown, the frame at least
shows up as TCP.
Instead of, in the TCP dissector, constructing a string and then
stuffing it into the Info column, just append to the Info column, which
avoids one string copy.
Pass a "frame_data" pointer to dissectors for TCP and IP (and PPP)
options, so they can use it to append to the Info column.

ESIS dissectors.
Register the IP dissector and have dissectors that call it directly
(rather than through a port table) call it through a handle.
Add a routine "tvb_set_reported_length()" which a dissector can use if
it was handed a tvbuff that contains more data than is actually in its
part of the packet - for example, handing a padded Ethernet frame to IP;
the routine sets the reported length of the tvbuff (and also adjusts the
actual length, as appropriate). Then use it in IP.
Given that, "ethertype()" can determine how much of the Ethernet frame
was actually part of an IP datagram (and can do the same for other
protocols under Ethernet that use "tvb_set_reported_length()"; have it
return the actual length, and have "dissect_eth()" and "dissect_vlan()"
use that to mark trailer data in Ethernet II frames as well as in 802.3
frames.

dissector.
Don't dissect the payload of any fragmented IPv6 packet unless it's the
initial fragment (that's what we do for IPv4).

This change allows you to add a new packet-*.c file and not cause a
recompilation of everything that #include's packet.h
Add the plugin_api.[ch] files ot the plugins/Makefile.am packaging list.
Add #define YY_NO_UNPUT 1 to the lex source so that the yyunput symbol
is not defined, squelching a compiler complaint when compiling the generated
C file.

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.

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.

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).
