1. Connection Manager parameter is called 'Redundant Owner' instead of 'Exclusive'
2. Add new CIP Class Names
3. Support new time types: UTIME, STIME, NTIME
4. Add units to data type
Notes:
1. There are no functionality changes with this delivery
2. This change is to reduce manual copying between structs. This will make it easier to add upcoming feature changes, and fix some connection handling issues (future merge requests).
3. Combine enip_conn_val_t and cip_conn_info_t. Previously, there were 2 different structs to track information about an overall CIP Connection.
Notes:
1. There are no functionality changes with this delivery
2. cip_connID_info_t describes a one-way connection. Each CIP Connection includes 2 of these. Previously, each operation was duplicated for each direction.
3. This change is to reduce copypaste, simplify logic, and make it easier to add upcoming feature changes, and fix some connection handling issues (future merge requests)

1. Dissect the Motion Configuration Block from the Forward Open

a special case that gets checked before this table. The default handling is
generic CIP Class 0/1 I/O.
2. Changed most I/O items labelled "ENIP" to "CIP I/O". ENIP is a separate

Dissection has been implemented directly in the packet-cip dissector,

Most attributes specify the path length before the EPATH data, but some do not. The previous code for parsing EPATHs just looped until there was no more data. This is a problem for EPATH that do not specify a length, because it will eat up too many bytes. This mainly affects Get Attribute List Responses and Set Attribute List Requests. For the small number of attributes like this, the Spec says exactly what kind of segment should be in the EPATH, so just parse a single segment.
This fixes: Port attributes: 'Port Number and Node Address' and 'Chassis Identity'
There is still one that is a problem in packet-cipsafety.c, but we will have to deal with it later. See the TODO in that file.

A dissector must never assume that it will, or won't, be called with a

whether to do it, and it can change its behavior over time or even
change it from release to release.

do so only if the tree pointer passed to it is null.

3. Enable enhanced Info column by default now that some of the additional wordiness was removed by the above points.
