file, instead of throwing out all but LANE or RFC 1483 data frames and
pretending that the former are just Ethernet or Token-Ring frames.
Add some level of decoding for ATM LANE, but not all of it; the rest,
including decoding non-LANE frames, is left as an exercise for somebody
who has captures they want to decode, an interest in decoding them, ATM
expertise, and time....

in dfilter-grammar.y) to a new struct dfilter. Display filters now have
their own struct, rather than simply being GNode's. This allows multiple
display filters to exist at once, aiding John McDermott in his
work on colorization.

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.

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]
notation: ether.src[0:3] == 0:6:29 instead of ether.srcvendor == 00:06:29
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!

values (for example, a sequence number in a TCP header should be printed
as an unsigned value; I have a trace in which the uppermost bit of the
sequence number is set...). If we need to be able to handle signed
values, add FT_INT{8,16,32} types.

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.

file formats. Libpcap is used only for capturing.
