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.

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".

as it standed depends on your lex being flex, but that only matters if you're
a developer. The distribution will include the dfilter-scanner.c file, so
that if the user doesn't modify dfilter-scanner.l, he won't need flex to
re-create the *.c file.
The new lex scanner gives me better syntax checking for ether addresses. I
thought I could get by using GScanner, but it simply wasn't powerful enough.
All operands have English-like abbreviations and C-like syntax:
and, && ; or, || ; eq, == ; ne, != ; , etc.
I removed the ETHER_VENDOR type in favor of letting the user use the [x:y]

I implemented the IPXNET field type; it had been there before, but was
not implemented. I chose to make it use integer values rather than byte
ranges, since an IPX Network is 4 bytes. So a display filter looks like this:
ipx.srcnet == 0xc0a82c00
rather than this:
ipx.srcnet == c0:a8:2c:00
I can supposrt the byte-range type IPXNET in the future, very trivially.
I still have more work to do on the parser though. It needs to check ranges
when extracting byte ranges ([x:y]) from packets. And I need to get rid
of those reduce/reduce errors from yacc!

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.
