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.

Get rid of the "tvb_compat()" call in the IPX dissector - it calls all
dissectors through handles or lookup tables, and thus any
backwards-compatibility stuff is done by the code in libethereal.

Handle the Content-Length: MIME header, so that, if there's a
Content-Length: header, we only process as RTSP payload the amount of
data specified by that header.
Handle frames with more than one RTSP message in them (the previous
change allows us to do so).

Still more work to do though, as I want to dissect the various message
types correctly, and to dissect TLVs much more as well.
The dissector currently handles multiple messages in a PDU, as the trace
file I have has some of those.
I think that the equipment that generated the LDP trace I have has a bug.
It seems to think that TLVs must be alligned on 4-byte boundaries, while the
spec (draft) says that there are no alignment requirements :-)
Don't know what generated the trace :-)

of the search if the caller-supplied limit goes past the end of the
tvbuff - the limit should just be what remains in the tvbuff after the
specified starting offset.
In "tvb_find_line_end_unquoted()", after searching for the next
interesting character, check the value we got back from that search, in
"char_offset", not whatever happens to be in "cur_offset", to see if we
found a character.

"proto_reg_handoff_wlan()", to match "proto_register_wlan()".
Call it "IEEE 802.11 wireless LAN", not "Wireless ethernet" - that makes
it clearer what type of wireless LAN it is (which *isn't* Ethernet at
the MAC layer, although I suspect many of the drivers make it look like
Ethernet to the rest of the system).

dissect_fddi_not_bitswapped() and dissect_fddi_bitswapped(), both of which
use the standard 3-argument tvbuffified-dissector argument list.
Add a dissector table called "wtap_encap" which is used to call dissectors
from dissect_frame(). The switch() statement from this top-level dissector
is removed.
The link-layer dissectors register themselves with the "wtap_encap"
dissector table. The dissectors are now static where possible.

in order to check whether to use ANSI C features such as "const".
GCC defines it as 1 even if extensions that render the implementation
non-conformant are enabled; Sun's C compiler (and, I think, other
AT&T-derived C compilers) define it as 0 if extensions that render
the implementation non-conformant are enabled; Microsoft Visual C++
6.0 doesn't define it at all if extensions that render the implementation
non-conformant are enabled.
We define it as 0 in "config.h.win32", so that those generated files will use
those features (and thus not get type warnings when compiled with
MSVC++).
