Michael: I guess you've updated the patch on behalf of Benjamin Stocks.

Thanks !

IMO, there are some more changes which need to be done ...

> Mixed tab/multi space indentation has to go.

There's still a lot of mixed tab/multi-space indentation and inconsistent
indentation (e.g. 6 spaces in some cases). 

There's also a fair amount of what I call "4 space tabs". Please
replace same by 4 spaces.

Please remove all trailing blanks.

1) Can you clean up some of the whitespace?  (e.g., hf_cip_control_status
declaration and others don't line up with the rest, value_string declarations,

As noted above: still needs work.

> 2) Didn't know when to use "extended" value string vs. "regular" value string

ans: for "large" value_string arrays (where "large" is somewhat arbitrary):)

I'd start with:

Speaking of which:
cip_gs_vals in packet-cipmotion.c is the same as that in packet-cip.c except
that the last two entries are missing. Do you know:  is this correct or should
the value_string arrays be identical ?  If they are identical, then please use
one common value_string; (actually just the extended value string pointer would
need to be public).

12) checkAPIs.pl finds the following problems:
$ tools/checkAPIs.pl epan/dissectors/packet-cipmotion.c
Warning: epan/dissectors/packet-cipmotion.c does not have an SVN Id tag.

$Id$ still missing;

Additional notes:

1. There's no prefs so prefs_register_protoco() need not be called (and
#include <prefs.h> is not needed, etc.

also: proto_reg_handoff...() doesn't need 'if (!initialized) ...' since no
prefs and thus this fcn is only called at Wireshark startup. 

cip_motion_handle isn't actually used so no need to call

2. Forward ref declaration for proto_register...() not needed.

In my experience, including this in the patch almost always works OK (assumimg
the patch is based upon a somewhat recent SVN).

Note: epan/CMakeLists.txt should also be updated.
